What happens if the app is no longer available for download from App Store/Google Play?

The previously installed app on your device will be available if the ability to download it from App Store/Google Play suddenly disappears.
The app works independently of Tangem's servers and will continue to work even if the company shuts everything down. You can also always download the Tangem app on GitHub. Moreover, the Tangem app is fully open source and available on GitHub, so a replacement app can be created by anyone and used to power the card.
