Minimalistic iOS Checkout

A simple minimalstic approach on the Credit Card checkout for iOS.

The idea is to streamline as much as possible but still giving control to the user. This should be the last step, following from the order.

The Creditcard field will be already on focus and the numeric keyboard should be already open - this is to reduce time and provide a clear next step for the user.

I am planning to animate this but since i am on a Windows machine i don't have access to the beautiful combination of Sketch + Principle.

Any suggestions on software that imports easily PSD's to animate on Windows?
