How it works
No equipment. No expensive hardware. Just your phone.
Your phone's camera. Any surface, any location. Solo or with a training partner.
Mark the precise start and finish — frame by frame. No guesswork, no reaction delay.
Precise time, Explosive Score, and your percentile rank vs athletes your exact age and gender.
Built for your sport
From grass to track, solo sessions to combine prep — precise sprint timing wherever you train.
A raw time means nothing without context. A 1.65 on the 10-yard means something very different at 14 versus 19. Male versus female.
Your Explosive Score gives you a percentile — 1 to 100 — benchmarked against athletes your exact age and gender, calibrated against NFL Combine data.
What you can measure
Each test isolates a different quality. Together they show where you're strong — and where there's ground to gain.
Explosive first step. The clearest signal of power from a standing start.
Full sprint velocity. The standard combine distance — your number against everyone else's.
Your true top speed, measured from a flying start so acceleration doesn't cap it.
Braking, pivoting, re-accelerating. Fast in a game, not just a straight line.
From the founder
"I built this because I couldn't find a tool that gave my sons a real number. After years of stopwatches and guesswork, I wanted precision that didn't cost $2,000 in hardware. Explosive Sprint Timer is as close as you can get to laser-gate accuracy — from the phone you already have."
