The iPhone app
The iPhone app is Amppfy in your pocket: the same account, the same Safe-to-Spend™ number, and the same math as the web. Anything you change on your phone shows up on your partner’s phone and on the web within a moment, and the other way around.
Same number, same math, in your pocket
Your Safe-to-Spend™ number with the status scale and the receipt under it, exactly what you would see on the web, from the same account.

One account, every screen
Same sign-in as the web, and your household is already there.
The iPhone app is ad-free. On the web, clearly labeled ads keep Amppfy free.
The widget
Your number in a ring, the status word, and the days to payday, on your Home Screen and Lock Screen.
Links open in the app
Partner invites and Amppfy links land where they should, signed in.
