The app will be like a 'test/quiz' games where users will have to answer in multiple questions or input their answers. I will elaborate more to the interested coder. The graphics will need to reflect the quiz game.
I will provide the entire data regarding the test or quiz. All you have to do is create the app that will be available on Android/Tablet and iPhone/iPad.
I will create milestones payment in different stages, from app building and testing to acceptance on both platforms and ensuring it's bugs free after launch.
