You can use apps you bought on Google Play on any Android device without paying again. However, each device must have the same Google Account on it. You can:
- Install an app on more than one Android device.
- Install an app on a new Android device.
- Reinstall an app you bought but deleted.
Also, if you turned off an app that came with your device, you can turn it back on.
Reinstall apps or turn apps back on
- On your Android phone or tablet, open Google Play Store .
- Tap Menu My apps & games Library.
- Tap the app you want to install or turn on.
- Tap Install or Enable.
Find previously purchased or downloaded apps
If you can’t find an app or are asked to buy it again, make sure you're using the same Google account you bought it with.
