321 Mountain Bike Timer

The telemetrics of F1 for you and me.
Factory sponsored riders have access to testing with all kinds of telemetry. Video recordings, shock set up recordings, acccess to professional coaches.

Most of us mortals do not. We want to change that and this stopwatch is the first step in that direction.

How does it work?
You attach a sensor to your bike frame and record your run. We look at when your bike actually moves. The GPS can lag behind a few seconds when you start and stop so instead we look at actual bike movement.

You must buy a piece of hardware, a Texas Instruments SensorTag for this app to work.
