Honest speed data, for every athlete.
SpeedTrackr exists because elite-level measurement shouldn't be locked behind prohibitive hardware costs. Two Android phones and honest numbers — that's the whole idea.
“I wanted real numbers instead of a human thumb on a stopwatch.”
SpeedTrackr was built by Dafin Edison — a competitive sprinter with 14 years on the track in Chennai. The difference between a good day and a bad day is hundredths of a second, but reliable measurement always meant hardware he couldn't afford.
By leveraging the processing power already in our pockets, SpeedTrackr brings validated timing and AI biomechanics to independent athletes everywhere.
Why SpeedTrackr exists.
Elite feedback, locked behind paywalls.
In India, getting real biomechanical feedback on your sprint form requires expensive labs and elite specialists. Most athletes — including me — never had access to that.
So I built the tool myself.
After 14 years of sprinting in Chennai and hitting plateaus I couldn't diagnose, I built SpeedTrackr — precision timing and AI biomechanics from a smartphone. No lab. No expensive gates. Just data.
Now I'm using it on myself. Publicly.
A 52-week scientific program, started June 2026. Every session logged, every time trial published. You'll see the numbers go up and down — that's what real development looks like.
