Decision's app Login/Register

Here is a preview of an ios & android auth process for an app that I am currently developing. I thought of the idea a while ago. Stay tuned for the designs of the actual app. I would love to hear some feedback. This is my first time developing and designing a mobile app for Ios and android at the same time. Thanks to react-native :P. Give me a like if you like what you see.

Ignore the slogan lol, I was just messing around.
The astronaut image was borrowed from hathayde.

Check out the high res version of the designs to get a closer look.

Thanks!
