Honest speed data, for every athlete.
SpeedTrackr exists because elite-level measurement shouldn't be locked behind prohibitive hardware costs. Two devices for timing gates (the second can be Android, iPhone, or a laptop) 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 using the phones and laptops athletes already carry, SpeedTrackr brings practice start and finish timing, jump, reaction, and bar speed to independent athletes. It does not analyze sprint form.
Why SpeedTrackr exists.
Elite feedback, locked behind paywalls.
In India, reliable practice timing meant expensive gates and 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 could not time cleanly, I built SpeedTrackr: practice-grade start and finish timing, jump, reaction, and bar speed from a phone or laptop. No lab. No expensive gates. No form AI. 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.
