Ballet Protractor is a ballet practice tool that measures your leg angles in real time with the camera. See exactly how many degrees your leg rises in a développé or split, and keep a record to track your progress over time. It also includes a Manual Protractor that measures any angle right on a photo — like your turnout. ■ Measures the angle between your legs Recognizes side développés as well as front and back extensions. ■ Real-time measurement + skeleton overlay Pose recognition draws your leg lines and the angle on screen in real time. Just step in front of the camera. ■ Record your practice on video Your best angle is shown live, and you can save the video to your gallery or share it. ■ Measurement history and progress chart Every session's best angle is saved automatically, with a thumbnail of that moment. Watch your angles grow at a glance on the chart. ■ Manual Protractor — any angle, on a photo Take a photo or pick one from your gallery, drag the V-shaped protractor into place, and measure any angle from 0 to 360°. For angles on the floor — like turnout — turn on the top-down fix: even a tilted shot is automatically straightened to a true top-down view for an accurate reading. Save or share the photo with the angle on it. ■ Offline · Privacy All measurement, video and photo processing, and record keeping happen only on your device. Recorded videos and photos leave the app only when you save or share them yourself. No sign-up required — measuring and recording work without internet. ■ Available in 5 languages Korean, English, Japanese, Russian, and French, shown automatically in your device language.
