Android Apps with Growing Potential

I just read a very interesting news piece on a unique Android application. What they have done is applied technology to football, and came out with something very impressive. Its called the "Replay Football system." It uses a Bluetooth enabled Nerf Football and an internal processing module with inertial sensing to analyze your throw. It allows real-time use and possibly soon, tips to improve your throw. Right now it includes the following performance measurements: Velocity, time in flight (in seconds), accelerometer, gyroscope, magnetometer, wobble, and spiral rotation speed.

Now, I have to admit, I'm not a huge football fan if you hadn't already guessed from my Technology Blog. But I do see this app growing a lot in the near future. I think this technology could grow to be used in all sorts of other things. Not just all other sports but every day activities. Imagine lifting weights and having an app to help you lift more effectively, or shoes to tell you your walking stats for the day. I'm not saying we are at that point yet but we could get there. What do you guys think?
