This application is just a clock.
...that has cheating capabilities built in.
Load up the application and a generic watch face will appear.
Shake or tap the watch and request an answer
Wait a little for someone to fill your request
When the request has been filled, you will recieve the answer
You will receive requests for answers. You can choose to answer or deny the request (be a team player).
When you accept the request, you will be able to choose an answer. It will then send the answer to all pebbles in the "room".
