*****Designed by sport scientists. Validation published on the Journal of Strength & Conditioning Research and Journal of Sports Sciences***** ***Featured by Apple under ‘Best New Apps’ in 100+ countries*** ***The only app which calculates the force-velocity profile using the groundbreaking Samozino’s method*** My Jump 2 is the first app scientifically developed to measure your jump height. With a great design and validated by sport scientists, My Jump 2 is as reliable as a 10000$ force platform. Scientifically probed! ------------------------------ Pierre Samozino (PhD, sport scientist, University of Savoy): “My Jump 2 makes possible the determination of the jump height with a high accuracy, which has been validated in very recent scientific study. The other, and I think the main added value of this app is to propose the determination of the Force-Velocity-Power profile of each athlete and its own imbalance between force and velocity qualities. Very useful to optimize your strength training and improve your explosive performances.” Jean-Benoit Morin (PhD, sport scientist, University of Nice): “My Jump 2 is the cutting edge, scientifically validated and most practical application to measure athletes vertical jumping performance, and the only one to include the complete "Optimal Force-Velocity Profile" analysis we recently validated. I'm using it with athletes, students, and research subjects. The entire Jumping Force-Velocity-Power and Optimal F-V Profile approach in your pocket!” ------------------------------ My Jump 2 gives you advanced information of your jumps using the camera on your iPhone, iPod touch or iPad. Just record a jump, select accurately its take off and landing and lets My Jump do its magic. My Jump 2 calculates the height, flight time, velocity, force and power of your vertical jumps. Also, it gives you the contact time, vertical stiffness and reactive strength index (RSI) of your Drop Jumps. Moreover, it allows you to calculate your Force-Velocity profile using Samozino's method. Complete analysis of your jumps right on your hand! FEATURES: • Accurate measurement of your vertical jumps.
