Install Soundsta.sh
Soundsta.sh doesn't exist as a native mobile / desktop app yet, but you can add the app to your home screen for a fullscreen, native-like experience - no app store needed.
Open in Safari
Make sure you're using Safari. The “Add to Home Screen” option is only available in Safari on iOS - Chrome and other browsers don't support it on iPhone/iPad.
Tap the Share button
At the bottom of the screen, tap the Share icon (a box with an arrow pointing upward).
Tap "Add to Home Screen"
Scroll down in the share sheet and tap Add to Home Screen. If you don't see it, scroll down further - it can be hidden below other options.
Confirm and add
A name field will appear pre-filled with “Soundsta.sh”. Tap Add in the top-right corner. The app icon will appear on your home screen.
