Film your throw on your phone. BetterDarts overlays your body's movement frame by frame — release point, elbow angle, follow-through — and tells you what to fix.

Prop your phone side-on to the throw line with your whole body in frame — that's the angle where your elbow and release are visible. Good light helps; 60 fps is a bonus.
The app draws a stick figure over your body on every frame, with your throwing arm highlighted. Slow it to 0.1× or step through the release frame by frame.
See your release point, elbow and shoulder angles, and wrist path — then compare all three darts of a turn side by side with a written read-out of your technique.
The app finds the exact frame the dart leaves your hand — by peak hand speed — so every throw is measured at the moment that matters.
Elbow and shoulder angles are labeled live on the video — watch how your elbow tracks from backswing to follow-through.
All three throws of a turn, side by side as stick figures, time-aligned at release. Inconsistency you can't feel becomes something you can see.
Plain-English feedback on the fundamentals: release repeatability, follow-through, shoulder quietness, and rhythm across your set.
