Full description
Turn two phones into a start and finish gate, plus jump, reaction, and video bar speed in one app. SpeedTrackr is for sprinters, track coaches, and strength athletes who want practice data without laser hardware. WHAT YOU GET • Timing gates. Pair a start phone and a finish phone with a 4-digit code. The finish phone can be Android, iPhone, or a laptop. You get the start-to-finish time, with a normal start or a reaction start. No split times. • Sprint-start reaction. An audio countdown and a false-start check for solo block work. • Vertical jump and RSI from phone video. No jump mat or force plate. • Video bar speed. Mean and peak velocity, velocity loss, range of motion, and bar path from a lifting clip. Nothing attached to the bar. • Coach tools. An athlete roster with records and results, in the Android app and on the web. HONEST SCOPE Practice-grade start and finish times. Not official fully automatic timing, and not a certified laser system. The Android app needs Android 10 or later.

What's new

- Timing Gates: when the finish camera only half sees your athlete, you get their photo and time to confirm instead of a miss. - Timing Gates: cancelling a run from the start phone no longer shows a "camera saw nobody" card.
