iPhone and Android

Flippo, on your phone.

Flippo works in your phone's browser and can sit on the home screen like an app: cards, watchlist and wallet cards one tap away. There is nothing to download and no store listing. A native app is not planned for now.

iPhone (Safari)

Open Flippo in Safari.
Use the Share icon and pick Add to Home Screen.
Launch Flippo from the icon it creates.

Android (Chrome)

Open Flippo in Chrome.
From the three-dot menu pick Install app (or Add to Home screen).
Launch Flippo from the icon it creates.

Your watchlist and saved cards live in each browser separately, so the phone starts empty. Push alerts for watched cards are planned, not built.
