I'd like to create an app for ios and android. My concept concerns sport and cross training challenge. So, i'd like to have Something like crossfitgames app, if you want an idea. I'll need to cumulate scores and sportmen/women performances, to create automatic ranking, to create individual members profils with a password acces, the possiiblity to create Survey, to insert pictures and videos, and I 'd like to include payment system. A push notification service should be include too.
So, maybe the best way could be to create a mini soft, to generate and update easily all rankings and profiles.
What is your opinion ?
