Svinga Loss

Svinga Loss turns a slow-motion video of your disc golf throw into motion trails of your arm, coloured by speed. • Film your throw in Slo-mo (120 or 240 fps) on your iPhone and pick the clip. • The app finds the throw, your throwing arm, the throw style (backhand or forehand) and the moment of release automatically. • Your arm's path is traced from the start of the throw to the release, coloured from blue (slow) through cyan and white to magenta at top speed. • See whether your speed builds into a sharp spike right at the release — the mark of an efficient throw — or stays flat for too long. • Snap ratio: how much faster the disc leaves than your hand moves. • Fine-tune start, release and throw style by hand, step the release one frame at a time, and choose how the trails look. • Save the traced video to Photos or share it. Everything runs on your iPhone. No account, no upload, no tracking. Tip: film side-on, with the whole thrower in the frame, in good light.
