It measures your time in the air.
Nothing more, nothing less. Your phone films the jump in slow motion; from the flight time, simple physics gives your jump height.
Film your jump
Record in slow motion — the more frames per second, the more accurate.
Mark take-off & landing
Pick the frame you leave the ground and the frame you land. That is your flight time t.
Get your height
VeJump turns the flight time into your jump height — the same method validated against force plates.
Jump height = (9.81 × t²) / 8
where t is your time in the air (the flight time)
Validated in studies: this video flight-time method correlates near-perfectly (r ≈ 0.99) with laboratory force plates.
You can’t improve what you don’t measure.
Whatever your goal — dunk, spike higher, land your jump serve, or simply beat last month — progress is invisible without a number. Measuring turns “I think I’m getting better” into proof, keeps you honest, and shows what is actually working in your training.
Go further for $1 a month.
The measurement stays free. Pro adds the tools that make tracking effortless.
