Delayed replay on one device

Tap Use this device, set the delay, and place the phone on a tripod facing the apparatus. Every routine plays again after the delay. Tap save to keep the last seconds.

A phone as the camera, a tablet as the screen

On both devices tap Connect devices, choose which one is the camera and which is the screen, and enter the code shown. Both devices should be on the same Wi-Fi network. On Android, a direct link also works without a network.

Getting good analysis results

• Keep the whole athlete in the picture, from take-off to landing.
• Film from the side when possible, with the camera still (a tripod is best).
• Good light helps; avoid strong backlight.
• If several people are in the video, choose the athlete in Analyze.
• A "?" means the app could not measure that part reliably. That is better than a wrong number.

Comparing two videos

Open a video, tap ⋯ and Compare with…. In Analyze, tap Take-off, Top or Landing to put both videos at the same moment, and tap a joint on a video to measure the same angle on both.

Where are my videos?

Only on your device, in the app's Library. Deleting the app deletes them, so save important ones to your gallery first.
