12 Best Free Mobile App Builders and App Makers in 2026 (Tested)
We tested 12 free mobile app builders and app makers in 2026 and checked what each free tier actually ships, not just what it lets you build.
You can build a real mobile app in 2026 without spending anything. What almost no roundup tells you is that on most of these tools free stops before you can actually publish. We tested 12 free mobile app builders, read every pricing page in October 2026, and checked one thing competitors gloss over: what each free plan actually lets you ship. Three of the twelve give you a real installable app without paying the builder. Full disclosure, our own builder is in this list, and because its free tier is a trial rather than free forever we ranked it 4th, not first.
What This Guide Delivers
- 12 free mobile app builders tested side by side
- What each free tier actually includes
- What you can genuinely ship without paying
- Honest pros and cons for every option
- Verified pricing read from each vendor in October 2026
- 12 FAQs on publishing, branding, AI and code export
Pricing read directly from each vendor in October 2026. “Free” varies: some tools are free forever (MIT App Inventor, Kodular), others are free tiers you cannot publish from, and one is a free trial. Google Play charges a one-time $25 registration fee and the Apple App Store charges a $99 annual developer fee. Those are Google’s and Apple’s charges, not the builder’s, and no free plan removes them. Rated 4.7/5 on G2 from 1,388 reviews.
TL;DR Quick Summary
Twelve free mobile app builders are worth your time in 2026, but they are not free in the same way. Only MIT App Inventor, Kodular and AppsGeyser hand you an installable Android app without paying the builder. Glide, Thunkable, Bubble, Adalo and FlutterFlow all give you generous free tiers to build in and then charge you to publish. Base44 and Jotform ship a web app for free. Appy Pie AI, our product, is the easiest route to a launched native app but its free tier is a trial, so we ranked it 4th. Starting from nothing? Read how to create an app first.

How We Tested These Free App Builders
Every builder was judged on the same six criteria, and pricing was read directly from each vendor’s own pricing page in October 2026 rather than carried over from an older roundup. Where a free plan blocks publishing, we say so and name the plan that unblocks it. If you would rather follow one build the whole way instead of comparing tools, building an app from a prompt is written as a single walkthrough.
What is actually free
Free forever, free tier, or trial, and exactly where the wall sits.
What it ships
Does the free plan end in an installable app, a web app, or nothing?
Beginner-friendliness
Can a first-timer finish something without writing code?
Output & platforms
iOS, Android or web, and how the result actually feels.
Verified pricing
Every price read from the vendor’s own page in October 2026.
Disclosure
Appy Pie AI is our product. Its free tier is a trial, so we ranked it 4th.
What You Can Actually Ship for Free
This is the table most free app builder roundups leave out. Every tool below has a free plan. Only three of them end with an app you can install without paying the builder a cent. The rest are genuinely useful places to build, and then ask for money at the moment you want other people to use what you made.
| Builder | What the free plan produces | Can you publish free? | What unlocks publishing |
|---|---|---|---|
| MIT App Inventor | Installable Android APK | Yes, on the free plan | Nothing; free forever |
| Kodular | Installable Android APK | Yes, on the free plan | Nothing; Premium (€3.99/month) only lifts limits |
| AppsGeyser | Installable Android APK | Yes, on the free plan | Extras only, from $58/month |
| Base44 | Web app | Web only | More credits, from $16/month |
| FlutterFlow | Web app (watermarked) | Web only | Code and APK download, $39/month |
| Jotform Apps | Web app | Web only | Higher limits, from $39/month |
| Google AppSheet | Personal or internal app | Internal use only | Wider sharing, from $5/user/month |
| Adalo | App with Adalo branding | No store publishing | Automated store publishing, $36/month |
| Glide | Project you can preview | No | Published apps, $25/month |
| Thunkable | Project you can preview | No | A live published app, $37/month |
| Bubble | Project under construction | No | Launch-ready hosting, $59/month |
| Appy Pie AI | Trial build | No | Publishing, from $16/app/month |
Google Play charges a one-time $25 registration fee and the Apple App Store charges a $99 annual developer fee. Those are Google’s and Apple’s charges, not the builder’s, and no free plan removes them. So even on the three genuinely free tools, listing publicly on Google Play still means paying Google once. The difference is that you are not also paying the builder every month.
RANK 01
Glide
Glide turns a spreadsheet or database into a polished mobile app without code. You point it at Google Sheets, Excel or Airtable, and it generates filterable lists, detail screens, forms and role-based access on top of that data. The result genuinely looks designed rather than auto-generated, which is why it keeps winning roundups like this one. The free plan gives you $0 per month, up to 10 projects, 2 team members and a limited pool of AI credits, so there is plenty of room to build and preview. The catch is publishing: the $25 per month Basic plan is the tier that adds published apps, so on the free plan you are building and previewing rather than shipping. Treat Glide’s free tier as the best place to prototype a data-driven internal tool, then budget for Basic the moment you want other people using it for real.
Strengths
- Turns Google Sheets, Excel or Airtable into an app in minutes
- Output looks genuinely designed, not auto-generated
- Free plan allows up to 10 projects and 2 team members
Cons
- Free plan does not include published apps; that starts at $25 per month
- AI features run on a limited credit pool
- Shaped around data apps rather than complex custom logic
RANK 02
Thunkable
Thunkable is the strongest free option if you want one project that targets both iOS and Android. You assemble screens by dragging components and wire behaviour with a visual blocks editor, so there is real logic available without writing code. The free plan includes 2,000 AI tokens, 3 public projects and 5 screens per project, which is enough to build and test a genuine multi-screen prototype on your own phone through the companion app. Paid tiers start at $18 per month billed yearly, or $19 billed monthly, for the Accelerator plan. Publishing is the thing to plan for: a live published app arrives on the Builder plan at $37 per month billed yearly, which also removes Thunkable branding. So the free tier is a real cross-platform workshop, and shipping is a deliberate paid step rather than an afterthought.
Strengths
- One project genuinely targets both iOS and Android
- Visual blocks editor gives real logic without code
- Free plan supports multi-screen builds you can test on a real device
Cons
- Free plan caps you at 5 screens per project and 3 public projects
- A live published app requires the Builder plan at $37 per month
- AI features are metered by token
RANK 03
MIT App Inventor
MIT App Inventor is the outlier in this list, and the reason it ranks this high: it is free forever with no paid tier at all. It is an open-source project run by MIT, built for teaching mobile computing, and it has no upsell waiting behind a feature wall. You compose screens and drag-and-drop logic blocks in the browser, test live on a connected device, and then export a finished Android APK you own outright. That export is what separates it from most tools here, where the free plan stops short of producing anything installable. The trade-offs are real: it is Android-first, the interface looks like the educational tool it is rather than a modern SaaS product, and you handle the Google Play listing yourself. If your definition of free means never paying anyone for the builder, this is the honest answer.
Strengths
- Free forever with no paid tier, no watermark and no feature wall
- Exports a real installable Android APK that you own
- Backed by MIT with a large, mature teaching curriculum
Cons
- Android-first; iOS support is limited to the companion app
- Interface feels like an educational tool rather than a modern product
- You handle Play Store listing and signing yourself
RANK 04
Appy Pie AI ★
Full disclosure before anything else: Appy Pie AI is our own product, and we have ranked it fourth rather than first because this is a guide about genuinely free tools and our free tier is a trial, not a free-forever plan. What it does well is remove every technical decision from building a real native app. You describe the app or pick a category template, and you get working navigation plus more than 200 ready modules covering push notifications, in-app payments, GPS, chat and bookings, with guided submission to both stores at the end. For a non-coder who wants a launched app rather than a prototype, that is the shortest path in this list. Paid plans run $16 per app per month for Basic, $36 for Gold and $60 for Platinum. If you want to build free and never pay, start at number three instead.
Strengths
- Shortest route from idea to a real native app for a non-coder
- More than 200 modules including push, payments, GPS and bookings
- Guided submission to both Google Play and the App Store
Cons
- The free tier is a trial, not free forever, which is why it sits at number 4
- Less customisable than code-first tools like FlutterFlow
- Priced per app per month rather than per account
RANK 05
FlutterFlow
FlutterFlow is the closest thing here to a professional development tool with a visual front end. You design screens on a canvas, connect APIs and databases, and it produces a real Flutter project underneath, which means the ceiling is far higher than a typical no-code builder. The free plan covers up to 2 projects, 10 Lite credits, API and data integration, and web publishing, so you can genuinely build and share something. What the free plan holds back is everything to do with shipping natively: downloading the project source code arrives on the Basic plan at $39 per month, and watermark removal, APK download and one-click store deployment all sit on paid tiers too. If you are a developer-adjacent team that wants to move fast without giving up code ownership, the free tier is a proper trial of a serious tool.
Strengths
- Generates a real Flutter project, so the ceiling is genuinely high
- Free plan includes API and data integration plus web publishing
- Visual canvas with far more depth than typical no-code builders
Cons
- Free builds carry a FlutterFlow watermark
- Source code and APK download start on the $39 per month Basic plan
- Free plan is capped at 2 projects
RANK 06
Base44
Base44 is the newest name on this list and the one Google’s own AI summary reaches for first on this topic, so it earns a place. What its free plan can and cannot ship is covered in our Base44 review. The model is simple: you describe the app you want in plain English, and it generates working screens, a data model and the logic behind them, which you then refine by talking to it rather than dragging components. The free plan gives you a monthly allowance of message credits with no credit card required, and those credits are the real currency here, since every AI message and integration action draws them down. Paid tiers run $16 per month for Starter, $80 for Premium and $160 for Elite. Two things make it unusually honest for an AI builder: you can keep apps private or publish them to the web, and the company confirms you own your app and can export the code. The output is a web app rather than a native store binary, so read it as the fastest way to get a working prototype in front of someone.
Strengths
- Describe an app in plain English and get a working build back
- Free monthly message credits with no credit card required
- You own the app and can export the code
Cons
- Credit-metered, and a free allowance disappears quickly on real iteration
- Produces a web app, not a native store binary
- Newest platform here, so the ecosystem is still thin
RANK 07
Bubble
Bubble has the deepest logic and database model of anything in this list, and if your app is genuinely complicated it is often the only no-code tool that can actually hold the requirements. Multi-step workflows, real relational data, conditional permissions and a very large plugin and template ecosystem all come standard. Its free plan is unusually clear about its own purpose: Bubble labels it for projects that are under construction, and the Starter plan at $59 per month is described as the tier for projects that are ready to launch. So free means a full-featured workshop you cannot ship from, which is honest but worth knowing before you invest weeks. Above Starter, Growth is $209 per month and Team is $549. The learning curve is the steepest here and costs climb quickly, so pick Bubble when the complexity genuinely demands it rather than by default. Bubble also leads the web-app category in our guide to the best no-code platforms, which ranks twelve platforms by job rather than by free plan.
Strengths
- Deepest workflow, database and permission model of any tool here
- Very large plugin and template ecosystem
- Free plan is full-featured for building and testing
Cons
- Free plan is explicitly build-only; launching starts at $59 per month
- Steepest learning curve in this list
- Costs rise steeply at Growth ($209) and Team ($549)
RANK 08
Adalo
Adalo is included partly because it is the page currently ranking first for this search, and it deserves the spot on merit: unlike most tools here it is built around real native mobile apps rather than responsive web pages, with a component model that maps cleanly onto phone interfaces. You can start on the free plan with no credit card and build a working multi-screen app connected to your own data. The limits are the familiar ones in a different order. Free apps carry Adalo branding, and the paid tiers are where removing that branding, using a custom domain and automated App Store and Google Play publishing all live. Starter is $36 per month and Team is $160. Read Adalo’s free plan as the most realistic rehearsal for a native launch in this list, provided you accept that the launch itself is a paid action.
Strengths
- Built around genuinely native mobile apps, not responsive web pages
- Free plan needs no credit card and supports real multi-screen apps
- Automated App Store and Google Play publishing on paid tiers
Cons
- Free apps carry Adalo branding
- Store publishing and custom domains are paid-only
- Record and action limits bite on the free plan
RANK 09
Google AppSheet
AppSheet is Google’s no-code layer over your own data, and for internal business apps it is very hard to beat. Point it at Google Sheets, Excel, Cloud SQL or its own built-in database and it generates tables, galleries, charts, maps, dashboards and forms, with automation for email, SMS and push notifications on top. Personal use is free with a Google account, which is why it belongs in a free roundup, and the paid tiers are priced per user rather than per app: Starter is $5 per user per month, Core is $10 and Enterprise Plus is $20. The limits worth knowing are structural rather than cosmetic. Database counts run 5, 10 and 200 across the tiers, rows per database run 2,500, 2,500 and 200,000, and genuinely public apps that anyone can open without signing in need a separate Publisher Pro subscription. This is a tool for approvals, inventory and field data capture, not for a consumer app you list on the stores.
Strengths
- Free for personal use with a Google account
- Excellent for approvals, inventory, HR and field data workflows
- Deep Google Workspace and Google Cloud integration
Cons
- Not designed for consumer apps you list on the app stores
- Row and database caps (2,500 rows per database below Enterprise)
- Genuinely public apps require a separate Publisher Pro subscription
RANK 10
Kodular
Kodular is the spiritual successor to MIT App Inventor with a considerably nicer face on it. The model is the same block-based drag-and-drop logic, but the component library is larger, the interface follows Material Design, and monetisation components are available for a one-time €15 activation plus usage-based pricing. Projects live in the cloud, previews run live on a connected device, and a single click generates your finished Android app, which is the part that matters in a list about free tools: like App Inventor, it produces something you can actually install and distribute. The free plan covers 10 projects, 10 MB of assets and 5 extensions per project, and Premium, at €3.99 a month, lifts those limits. The trade-offs are that it is Android only, block-based logic becomes unwieldy once an app grows past a certain complexity, and support is a community forum rather than a vendor with an SLA.
Strengths
- Free, and exports a finished installable Android app in one click
- Larger component library and cleaner interface than App Inventor
- Monetisation components available (one-time €15 activation)
Cons
- Android only, with no iOS output
- Block-based logic gets unwieldy on larger apps
- Support is a community forum rather than a vendor SLA
RANK 11
AppsGeyser
AppsGeyser has been converting web content into Android apps since 2011 and says it has produced more than 11 million apps, with around 3,000 created daily. Its pitch is the bluntest here: the basic features are completely free for everyone, and you finish with an Android app you can send to Google Play or share as a direct download link. If what you actually need is your existing site, blog or store wrapped into something installable, this is the fastest free path in the list and it does not ask for a card. Paid plans exist for the extras and start at $58 per month for Starter, with Individual at $98 and Master at $238. The honest limitation is the nature of the output: a wrapper around web content behaves like web content, so it will never feel like a purpose-built native app, and it is Android only.
Strengths
- Basic features are genuinely free and produce an installable Android app
- Converts an existing site or web content in minutes
- Built-in monetisation and push notification options
Cons
- Android only
- Free output is a wrapper around web content, not a native experience
- Paid plans jump straight to $58 per month
RANK 12
Jotform Apps
Jotform Apps is the narrowest tool here and the most likely to be exactly right for a specific job. It bundles forms, payment collection, appointment booking and simple content into a single app-like container that runs in any phone browser, with no install step for the people using it. If your app is really a set of forms plus a process behind them, which describes a great many internal and small-business apps, you can assemble it in an afternoon. The Starter plan is free, and paid tiers are Bronze at $39 per month, Silver at $49 and Gold at $129, with Bronze covering 25 forms and 1,000 monthly submissions. Because it is a web app rather than a store listing, the free tier can genuinely put something usable in someone’s hands today, which is more than most free plans in this list manage.
Strengths
- Fastest route from a set of forms to something people can actually use
- Free Starter plan, and no install step for end users
- Payments and appointment booking are built in
Cons
- Shaped around forms and workflows, not general app building
- Web app rather than a native store listing
- Submission and form limits apply on every tier
Also Considered
These four have real free offerings and come up often, but each is aimed somewhere slightly to the side of “I want a free mobile app”, so they did not make the main ranking.
SAP Build Apps
A real free tier, but it is aimed at enterprise teams already inside SAP. Overkill for a first mobile app.
Softr
Excellent for turning Airtable into a client portal or internal tool. Free plan available, paid from $19 per month, and web-first rather than native. If Airtable itself is the problem, see nine Airtable alternatives compared.
Budibase
Open source and self-hostable, which makes it genuinely free if you run it yourself. Built for internal tools rather than consumer apps.
Bravo Studio
Turns a Figma design into a real mobile app, so it suits design-led teams. The free tier is a trial of that pipeline rather than a place to ship from.
Which Free App Builder Should You Use?
What Is the Best Free App Maker? The Short Answer
An app maker and an app builder are the same kind of tool under two names. Which free one is best depends on what you are making:
Free forever, a real Android app
MIT App Inventor. No paid tier at all, and it exports an app you can install. Kodular if you want a more modern look.
One project for iPhone and Android
Thunkable. Free to build for both platforms; a live published app is on a paid plan.
An app from a spreadsheet
Glide. The most polished free plan for a data app you can build and preview.
Describe it and let AI build it
Base44. Free monthly credits turn a plain-English description into a working web app.
A website you already run
AppsGeyser. Wraps a site into an installable Android app with its free basic features.
A store app without code
Appy Pie AI (our product). The easiest route for a non-coder, but the free tier is a trial and publishing is paid.
Match your situation to one row. The question that decides it is not which tool is best in the abstract, it is what your version of free has to include: a learning project, a private prototype, or something strangers can install.
| If you are… | Pick | Why |
|---|---|---|
| You want to pay nothing, ever, and still install a real app | MIT App Inventor | Free forever, exports an APK you own |
| You want the nicest genuinely free Android builder | Kodular | Free, one-click APK export, Material components |
| You already have a website and just want it installable | AppsGeyser | Free web-to-app in minutes |
| You want the best free tier to build and prototype in | Glide | Polished output, 10 projects free |
| You need one project for both iOS and Android | Thunkable | True cross-platform, free to build |
| You want to describe the app and have AI build it | Base44 | Free monthly credits, code export |
| Your app has genuinely complex logic and data | Bubble | Deepest no-code data and workflow model |
| You want to own real code eventually | FlutterFlow | Produces a real Flutter project |
| You are building an internal tool on data you already have | Google AppSheet | Free for personal use, deep Google integration |
| Your app is really forms plus a process | Jotform Apps | Free Starter plan, usable today |
| You are a non-coder who wants a launched native app | Appy Pie AI | Easiest path; free tier is a trial, publishing is paid |
| You want a realistic rehearsal for a native store launch | Adalo | Native-shaped, store publishing on paid |
If you are still unsure, work backwards from the finish line. Decide whether anyone outside your team needs to open the app. If yes, pick from the three tools that publish free, or budget the monthly plan now rather than discovering it after the build.
The Fees No Free Plan Removes
Google Play charges a one-time $25 registration fee and the Apple App Store charges a $99 annual developer fee. Those are Google’s and Apple’s charges, not the builder’s, and no free plan removes them. That catches people out more than any builder limit, because it arrives at the end, after the app is finished and the excitement is highest.
Build Your First App Free
Appy Pie AI lets a non-coder build a real native app free to start, with push notifications, payments and maps built in, and guides you through publishing when you are ready.
Try Appy Pie AI FreeView PricingFrequently Asked Questions
Is there a totally free app builder?
Yes, three of the twelve we tested. MIT App Inventor has no paid tier at all, Kodular exports an installable app on its free plan (its €3.99 a month Premium only lifts limits on projects, assets and extensions), and AppsGeyser says its basic features are completely free for everyone. All three produce an installable Android app. Most other free plans in this list let you build and preview but stop before publishing, so read them as free workshops rather than free launchpads.
How do I build a phone app for free?
Decide first what free has to include. If it must include a finished, installable app, start with MIT App Inventor, Kodular or AppsGeyser. If free only needs to cover designing and testing, Glide, Thunkable, Bubble and FlutterFlow all give you generous free tiers to build in and you pay only when you want to ship. Either way, budget separately for Google’s $25 one-time fee or Apple’s $99 annual fee if you intend to list on a store.
Can ChatGPT build me an app?
ChatGPT can plan features, write code and debug it, but it does not host, compile or publish an app for you, so you still need a development environment and a developer account to end up with something installable. If you want a working app without handling any of that, an AI app builder is the closer match. Base44 turns a plain-English description into a working build, and Appy Pie AI does the same with native store submission at the end.
Can ChatGPT build an Android app?
It can generate Android code in Kotlin or Java and explain how to assemble it, but you would still install Android Studio, configure the SDK, create a signing key and pay Google’s $25 registration fee to publish. For most people who simply want an Android app rather than to learn Android development, a no-code builder such as Kodular or MIT App Inventor reaches an installable APK far faster and with nothing to compile.
What is the best free mobile app builder in 2026?
It depends on which kind of free you need. Glide has the best overall free tier for building data-driven apps, Thunkable is the strongest free cross-platform builder, and MIT App Inventor is the only option here that is free forever and still exports an app you can install. Appy Pie AI, our own product, is the easiest path for a non-coder but its free tier is a trial, which is why we ranked it fourth rather than first.
Can I publish an app to Google Play or the Apple App Store for free?
Rarely, and for two separate reasons. First, most builders put publishing behind a paid plan: Glide from $25 per month, Adalo from $36, Thunkable from $37, Bubble from $59, and Appy Pie AI from $16 per app per month. Second, the stores charge their own fees regardless of the builder, with Google Play taking a one-time $25 registration fee and Apple charging $99 per year. MIT App Inventor, Kodular and AppsGeyser at least let you reach an installable APK without paying the builder.
Which free app builder is best for Android only?
MIT App Inventor, Kodular and AppsGeyser, and notably these are the same three that let you produce an installable app without paying. App Inventor is the best for learning how apps work, Kodular is the most pleasant to use day to day and adds built-in monetisation, and AppsGeyser is the quickest if you are wrapping an existing website rather than building from scratch.
Which free app builder is best for iOS and Android together?
Thunkable is the strongest free choice, because a single project targets both platforms and you can test on a real device through the companion app. FlutterFlow is the better pick if you care about owning real code later, and Adalo is the most native-shaped of the three. On all three, building is free and publishing is the paid step, so plan for Thunkable’s Builder plan at $37 per month or FlutterFlow’s Basic at $39.
Do free app builders put their own branding or ads in my app?
Several do, and it is usually the first thing a paid plan removes. FlutterFlow applies a watermark on free builds and sells watermark removal on paid tiers. Adalo lists removing Adalo branding as a paid feature. AppsGeyser and Kodular both offer monetisation components (Kodular charges a one-time €15 to activate them), which means ads are a deliberate option rather than something imposed on you. MIT App Inventor applies no branding at all.
Can I export my app’s source code from a free app builder?
Sometimes, and it is worth checking before you invest months. Base44 confirms you own your app and can export the code. FlutterFlow generates a real Flutter project but puts the source download on its $39 per month Basic plan. MIT App Inventor and Kodular give you a finished APK rather than a codebase to maintain. Most other no-code builders, including Appy Pie AI, host the app on their own infrastructure and do not hand over source code.
What is the best free app maker?
There are three good answers, depending on what free has to cover. MIT App Inventor is the best free app maker if you never want to pay: it has no paid tier and exports an Android app you can install. Glide has the most polished free plan for building a data app, and Thunkable is the strongest free option when one project has to cover iPhone and Android. An app maker and an app builder are the same kind of tool, so every ranking on this page applies to both names.
What is the best app maker for beginners?
For a first app, pick the tool with the least to learn for the app you have in mind. Glide starts from a spreadsheet, so there is no logic to wire up. MIT App Inventor is designed for learning and snaps logic together as blocks. Base44 builds from a plain-English description, and Appy Pie AI, our own product, is the easiest route to a store app for a non-coder, though its free tier is a trial. If you are willing to pay for a tool that writes the code for you, see the best AI web app builders.
The Best Free App Builder Depends on Which “Free” You Need.
If free has to mean a finished app you never paid for, the list is short: MIT App Inventor, Kodular and AppsGeyser. If free means a serious place to build before you commit, Glide, Thunkable, Bubble, Adalo and FlutterFlow are all excellent and each names its publishing price openly. And Appy Pie AI, full disclosure our own product, is the easiest route to a launched native app, ranked 4th here because its free tier is a trial.
