About ForceData

ForceData is a very simple app that uses the sensors of the iPhone, iPad or Apple Watch to measure acceleration, velocity and force. Also, it exports filtered data to a CSV file. This CSV file is already prepared to plot force-time, velocity-time and acceleration-time curves easily.

Very useful for simple sport biomechanics analyses in exercises like the countermovement jump or the squat!
