Throw
DiscLab detects every throw and calls out the speed, so you work through the stack without touching the phone.

Throw. Review. Improve.
DiscLab measures your release speed with nothing but your phone's camera — no sensor disc, no extra gear. It detects every throw, calls the speed out loud, and saves the clip, so you keep throwing and the numbers keep coming.

How it works
Accurate throw measurements from your phone.
DiscLab checks your camera setup before you throw, and if a throw can't be measured reliably it says so — you'll never see a number it made up.
Review
Every throw is saved with its speed and its clip. Scan the session, spot the outliers, watch what you did differently.
Improve
Compare sessions over time and see whether a form change actually moved your numbers — or was one good day.
