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 four lines under it — exactly what you’d 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.
Changes travel both ways
Update a balance here and the web shows it within a moment — and back.
Links open in the app
Partner invites and Amppfy links land where they should, signed in.
