What it does
- 01
Finds the joints for you
Pose detection identifies shoulders, elbows, wrists, hips, knees, ankles, spine and neck, and overlays the joints and skeleton on your photo.
- 02
Any angle in three taps
Take a photo or pick one from your library, then tap the start point, the joint center and the end point.
- 03
Several people, color-coded
Detects multiple people in one photo and color-codes them, for group assessments.
- 04
Record it, track the change
Save each measurement with a name, joint label and notes. The original photo and an annotated version are both kept, so you can follow flexibility and recovery over time.
