The closest Kodular alternatives are MIT App Inventor and Niotron (the same blocks approach), Thunkable (blocks, cross-platform). If your app is really a website or web app, a URL or HTML to APK maker is faster than rebuilding it in blocks; if you've outgrown blocks, move to Android Studio or Flutter.

Compared
| Tool | Approach | Choose it when |
|---|---|---|
| MIT App Inventor | Blocks, free, educational | You're learning or teaching |
| Niotron | Blocks (App Inventor family) | You want App Inventor plus extras |
| Thunkable | Blocks + drag-and-drop UI | You also need iOS |
| HTML to APK | Your HTML/JS, bundled | You can write or generate web code |
| Website to APK | Your live site | The app is your website |
| Android Studio | Kotlin | You need everything native |
Blocks vs web code
Blocks are friendly but slow to edit at scale and tied to the platform. Web code (HTML/CSS/JS) is portable — the same files run in a browser, in an Android app and on a website — and AI assistants write it well. If you're comfortable asking an AI for code, the HTML route is often quicker than dragging hundreds of blocks.
Moving an App Inventor-family project to web code
You can't convert an .aia project to HTML automatically, but the logic usually maps cleanly:
| Kodular / App Inventor | Web equivalent |
|---|---|
| Screen | A section or page shown/hidden with JavaScript |
| Button.Click block | button.addEventListener('click', …) |
| TinyDB | localStorage |
| Clock component | setInterval |
| Web component | fetch() |
| Notifier | alert() or a custom dialog |
Paste a description of your blocks into an AI assistant and ask for a single-file HTML version — then build it with HTML to APK.
