We need an app for iPhone and Android where i can see a list of people around me with the same app running, and connect to them ( bluetooth? )
After we connect, i can touch a "Im ready" button, and the other party will notice that, and can also touch "im ready".
After both are ready, a countdown starts, from 5. when it hits 0, an alarm rings for both EXACTLY AT THE SAME TIME, IT **NEEDS** TO BE AT THE SAME TIME, this countdown needs to be 100% sync between both devices.
After the alarm rings, after a while, one of them will touch "I won!", and the other device will show "The other player won. Confirm?". If he touchs "YES", the round is over and the app saves this data. Who wins from who. This data can be shared online via regular php post to our website.
Waiting for reply.
