Banking & finance apps on iPhone Duo
Of the 25 popular banking & finance apps we track on the US App Store, 8 are confirmed to fill iPhone Duo’s inner display, including Cash App, Robinhood and Fidelity Investments. 16 still show black bars or unused space, including Venmo, Capital One Mobile and Wells Fargo Mobile. 1 isn’t confirmed yet.
Banking apps update slowly and many have no iPad version, so many still show black bars on the inner display. They work normally on the outer display, which is a phone-sized screen.

Questions
Which banking & finance apps work on iPhone Duo?
All of them run on iPhone Duo. Of the 25 we track, 8 are confirmed to use the whole inner display: Cash App, Robinhood, Fidelity Investments, Kalshi, Wise and Revolut.
Do banking & finance apps have black bars on iPhone Duo?
16 of the 25 we track show black bars or unused space today, including Venmo, Capital One Mobile, Wells Fargo Mobile, Chase Mobile and Intuit Credit Karma. Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display until the developer ships an update built with the iOS 27.1 SDK. On the outer display they look normal.
Do banking & finance apps work on iPhone Duo’s outer display?
Yes. The 5.4-inch outer display works like a regular iPhone screen, so every app runs there at normal phone size.
