GravNav is a simple Android app to help make city exploration more random and fun. When you get to a street corner, simply enter the number of choices you have and shake the phone. Once the arrow stops you know which street you should walk down next.

Future plans

• Change graphics from using an arrow to using sectors on a ring (might look better)
• Implement stats engine, tracking the number of options entered and the result that the randomization produced
• Implement random algorithm that doesn’t use rotation and “friction” to choose the end result
