Angles - Video Goniometer

This goniometer tool can be used to measure angles at various times in a video. Designed for rehabilitation professionals.

Features:
• Capture new videos or import existing videos from your library
• Step frame-by-frame through a video, or drag the slider to seek to a specific time
• Select points and drag them into place
• Lines and angle measurements automatically appear, connecting the points
• Repeat with more frames, points, and angles
• Export to spreadsheet (.xlsx format) for further calculations and analysis (note that there are multiple worksheets - one with raw point coordinates, and one with angle measurements)

Make sure to capture your video directly perpendicular to your subject, with the camera level in all planes, and without panning the camera.

The display of angle labels can be turned on/off in the apps preferences, found in the Settings app.
