CrossMobile: iOS app prototype for a mobile operator

34 iOS screens built as a clickable prototype: the home screen in three layouts, five flows from start to finish, two edge states and a dark variant. Sections follow the user journey.

CrossMobile is a Polish mobile operator. The iOS app prototype was made at CyberNinja.Digital in 2026. It holds 34 screens in iOS 26 components and five flows: first launch, paying the bill with BLIK, buying a data package, eSIM activation and number porting. The shots below come from the prototype; the app was not published in the App Store.

Two directions for the home screen

Before the final version, we drew the home screen in two layouts and compared them one to one. The first leads the eye with the amount due, the second with the package counter. The first one won: the bill is what a customer opens an operator app for most often.
