I need to have an Android and iPhone app to be designed and developed. The app will be a live score app for football. There will be several social features in the app, you should be able to invite friends to leagues, add friends, share things on Facebook, local & global highscore, registration through Facebook or e-mail, sound notifications for new goals etc. You should be able to connect with other users even if you don't use the same platform (i.e. Android users should be able to connect with iOS users).
Detailed requirements will be shared with the selected freelancer.
Three important things:
Very user friendly functions.
Professional, unique and top notch design.
Should work on all Android and iOS phones and tablets.
