Ballet Protractor

Measure the split angle between your legs in real time, and keep your best record every day.

Measures how far your legs open — not the knee bend. Your pose is detected and the angle is shown large on screen.

Record videos with the measured angle burned in, then save them to your gallery or share them.

Each session's best angle is saved automatically, and a chart shows your improvement at a glance.

Includes a protractor tool to measure any angle on a photo you take or pick. Floor angles like turnout are auto-corrected even from tilted shots.

Camera frames are processed on your device only — never sent to a server. No sign-up required.
