Pick your build method before you pick a brand. If you want to describe an app and let AI build it, choose a prompt-to-app builder. If you like dragging blocks and learning as you go, a visual builder fits, and if you already have a good website, a converter turns it into an app fastest.
No-code mobile app building has split three ways, and that's the most useful thing to know before you replace Thunkable:
- Prompt-to-app builders turn a written description into a working app.
- Visual block builders let you drag screens and logic together yourself.
- Website-to-app converters wrap the site you already run in a native app.
Thunkable itself now starts from a prompt, so many of its users are really choosing between these three, not between nine near-identical tools. The list below covers all three, in no particular order, for founders, educators and small businesses who want an iPhone and Android app without hiring developers.
Prompt, blocks or website: three ways to build
Start from a prompt
Vibecode, a0.dev and Rork all begin with a description. You type what the app should do, the builder makes a first version and you refine it with more prompts. It's the quickest way to see a working screen, and the hardest to control in detail. AppMaster sits close by with a no-code platform that also generates source code, which matters if a developer may take over later.
Start from visual blocks
Kodular, MIT App Inventor and Mobiroller use visual designers and blocks of logic. You build each screen yourself, which takes longer but teaches you how your app works. That's why one of them is built for classrooms, and why small businesses with a clear idea of their app often prefer this route.
Start from your website
Median.co and MobiLoud take an existing website and turn it into native iOS and Android apps. If your site already does the job, this is the shortest path to the stores. The difference between the two is how much they do for you: one is a converter you drive yourself, the other designs, builds and maintains the app as a service.
The nine app builders, alphabetically
Each entry below reflects how the vendor describes its own product.
a0.dev
Best for: Founders who want an AI builder for iOS and Android apps that deploy to the App Store and Google Play from one project.
AppMaster
Best for: Businesses needing backend, web and native mobile apps together, with the vendor saying it generates production-level source code; a free plan is named.
Kodular
Best for: Makers who want a drag-and-drop designer and no coding, which the vendor describes as much more than a modern app creator.
Median.co
Best for: Owners of a working website who want native iOS and Android apps from a URL, with store publishing included; the vendor says it's free to try.
MIT App Inventor
Best for: Students and teachers building working iPhone and Android apps in the browser, from a tool aimed squarely at education.
MobiLoud
Best for: Ecommerce and content sites wanting a custom app designed, built and maintained for them, and the vendor says site changes update the app automatically.
Mobiroller
Best for: Small businesses wanting Android and iOS apps designed, built and published without code, with a free plan named on the vendor's site.
Rork
Best for: Builders who want one AI-made app across iOS, Android and web, with store publishing as part of the pitch.
Vibecode
Best for: Non-developers who want to describe an idea, get a working iPhone, Android or web app and publish it to the App Store, as the vendor puts it.

Advice for founders and teachers choosing an app builder
If you're testing an idea and want something on your phone this week, start with a prompt-to-app builder and accept that you'll rebuild later if the idea works. If you're teaching, or you want to understand every screen, a visual block builder is the calmer choice. If your business already runs on a good website, don't rebuild it as an app from scratch: a converter will get you into the stores with far less work.
Whichever way you go, build one small but real feature in your top two choices before you commit, such as a sign-up screen or a booking form. You'll see quickly which tool fights you and which one doesn't. For more builders, see my FlutterFlow alternatives and my roundup of no-code mobile app builders.
Before you publish: the stores, and leaving later
Getting an app built is only half the job. Apple and Google each review apps before they appear, and every builder handles that step differently. Some publish for you, some guide you through it and some hand you a file to upload yourself. Ask which one applies before you start, because it changes how much work sits on your desk at launch.
Think about leaving, too, even though you've only just arrived. Some builders let you export source code or a project file, and some keep your app tied to their platform for good. If there's any chance a developer will take your app further, favour a tool that lets you take your project with you. It's much easier to ask that question now than after a year of building.
Finally, check who owns the store listing. Your app should sit under your own developer accounts with Apple and Google, not the builder's, so your reviews, downloads and listing stay yours if you switch tools.

Frequently asked questions
What's the difference between a prompt-to-app builder and a visual builder?
A prompt-to-app builder creates screens and logic from a written description. A visual builder has you place screens and logic blocks yourself, which takes longer but gives you more control.
Can I turn my website into an app without coding?
Yes. Website-to-app converters wrap your existing site in a native iOS and Android app. It works best when your site already runs well on a phone.
Will my app be accepted by the App Store and Google Play?
That's up to Apple and Google, and their review rules change. Read their guidelines before you build, and check how your chosen builder handles store submission.
Can I move my app to another builder later?
Sometimes. Some tools export source code or project files and some don't. Check before you start if you think you might switch or hand the app to a developer.
Are no-code app builders good for teaching?
Visual block builders are widely used in classrooms because students see how each part of the app works. Prompt-based tools are quicker but teach less about the logic underneath.
Do I need my own developer accounts with Apple and Google?
In most cases you should have them, so the app listing belongs to you. Check each builder's publishing steps to see which accounts it expects you to use.
