Why install it? It’s a real app — with no store
MateStorm is a Progressive Web App. Add it to your home screen and it opens full-screen with its own icon, just like a native app — but there was no Play Store or App Store step, no APK to sideload, and nothing to sign up for. Clear it from your home screen and it’s gone; there’s no leftover storage or permissions.
How to install without the app store
- Open MateStorm in your browser.
- Add it to your home screen (steps per device below).
- Launch it from your home screen any time — it opens like an app.
Install on Android
In Chrome you’ll see an Install app prompt, or use ⋮ menu → Add to Home screen. Note: this is not an APK — there’s nothing to sideload and no “unknown sources” warning. If you searched for an apk to skip the Play Store, this is the cleaner way to do it.
Install on iPhone and iPad
In Safari, tap the Share button → Add to Home Screen. iOS only offers this in Safari — Chrome on iPhone has no install prompt, so use Safari for this step. After that it launches from your home screen like any app.
