Need Iphone and Android App to:
1. Lock phone
2. Requires user to calculate simple math problems to unlock
3. The app should have End User settings to set when the lock will occur (every 5, 10, 15 mins etc)
4. User override of the lock by putting in a password
5. Should be a simple back end for us to add/create our own math problems that is not accessible to the end user.
The app needs to be app store ready and android market ready.
