Built on Applied Kinematics
We don't just "guess" based on height perception. SpeedTrackr uses the Flight Time Method, the same principle used by electronic jump mats in professional combines.
Identify Frames
Pinpoint the exact frame your toes leave the ground and land.
Extract Time
Calculate hang time to 3 decimal places using video metadata.
Constant G
H = 1/8 * g * t²
Using 9.81m/s² to derive 100% accurate vertical height.
Why Use SpeedTrackr?
Optimized for volleyball players, basketball athletes, and elite sprinters who need data, not guesses.
Flight Time Lab
Calculate jump height with laboratory-grade precision by marking takeoff and landing frames.
Power Metrics
Get estimated peak power (Watts) and relative power (W/kg) based on your jump height and bodyweight.
Takeoff Velocity
Understand your rate of force development by measuring how fast you leave the ground.
Progress Tracking
Save every session and view your jump height trends over months and years of training.
