I remember the Admin talking about the use of a mobile application for carrying out the lottery activities. I guess the application would be available for both android and iOS users and that would be the major way to communicate with the project.
Yeah, they need to make sure they design both android and iOS most project design just for IOS and take a lot time to design the android version
The designing and launching of mobile applications should be done at the same time. I don't like the the idea of designing for ios users before designing for android users. Infact, I have a belief that there are much more android users and in situations where the project cannot afford to launch both simultaneously, the android app should be launched first.
