Know your real rank

Your time.
In context.

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.

A score of 74 means you're faster than 74% of athletes your age and gender. That's the kind of number you can train with.

Four tests. One complete picture.

Each test isolates a different quality. Together they show where you're strong — and where there's ground to gain.

10yd / 10m

Acceleration

Explosive first step. The clearest signal of power from a standing start.

🏃
40yd / 40m

Speed

Full sprint velocity. The standard combine distance — your number against everyone else's.

🚀
Flying start

Max Velocity

Your true top speed, measured from a flying start so acceleration doesn't cap it.

5-10-5 shuttle

Agility

Braking, pivoting, re-accelerating. Fast in a game, not just a straight line.

"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."
