Very good. Some feedback:
1) Change the selection state on the bottom icons. If you reach question 2, then question 1 should show a tick
2) Change the picture on screen 1. Maybe a picture with lots of question marks ???
3) On the final screen change the picture, to show a picture of a closed safe/ vault
4) Next to the attempts remaining you should have a Buy more button. And this will go to a page with in app purchase to buy more attempts?
5) What does the ( i ) do in top right corner?
