Credit Card Checkout: Daily UI #002

I'm a little late, but here it is. Generic app. The first screen is blank, next one is full of information and the screen below is an user feedback.

I wanted to work a with gradients so I searched for some gradient generator and I came up with this one.
I opened an app of delivery and it inspired me too.

The vault icon is from flaticon. I used ios 11 components.
