Install an Android app maker that builds in the cloud, paste a website URL or pick an HTML file from your phone's storage, set the name and icon, and tap build. The server compiles and signs the app; you download the APK and install it on the same phone.

Get your content onto the phone
| Content | How to get it on a phone |
|---|---|
| A website | Just the URL |
| HTML from ChatGPT/Gemini | Copy the code, save it as index.html with a text-editor app |
| A ZIP of a site | Download it to the Downloads folder |
| An icon | Any square image in your gallery — 512 px or more |
Build on the phone
- Install the makerWebsite to APK or HTML to APK.
- Create the appSource, name, icon, colour.
- Tap build and waitKeep the app open or come back; the build runs remotely.
- InstallOpen the APK. Android asks once to allow installs from this app — allow it.
Phone-only tips
- Use Chrome to preview your HTML file before building.
- Rename files carefully —
index.html.txtis a common accident with editor apps. - Uninstall before reinstalling only if Android says the signatures don't match.
Updating your app later — still from the phone
For a URL app, just update the website. For an HTML app, edit the file, rebuild in the maker with a higher version number, and install the new APK over the old one — Android keeps the app's saved data because the package name and signing key are the same. If Android says "App not installed", the new build was signed with a different key; rebuild from the same project in the maker.

Can I code an Android app on my phone?
You can write HTML/JS on a phone and build it with HTML to APK. Writing native Kotlin on a phone is possible with special IDE apps but much harder.
