Gaming App (iOS/Android)

Hello, i am looking for a developer who can build a real time game app in iOS and Android. - Location based game with shooting a photo - ios and android - landing page website - Full Copyrights - Admin tool: We can watch the sequence in which a player photographs his opponent as a video and have the GPS data of the players. That way, we can make sure everything is right in the game. - No upfront payment. I will pay once the app is completly tested and finished. Once the app is done i will upload the money, not before. Thanks.
