BetterForm | Video Analysis

Stop guessing what changed. Put two clips side by side, scrub them in sync, slow it down frame by frame, and draw the difference — all on your device.

BetterForm is the fastest way to compare your form, side by side.

Record or import two clips, line them up, and scrub them together in slow motion to see exactly what separates a good rep from a great one. No coaching platform, no account, no cloud — just you and your video, private on your device.

COMPARE SIDE BY SIDE • Stack two clips top and bottom and play them together. • Tap Link to sync the two playheads — line up the key moment in each clip and they move as one. • Fine-tune the alignment one frame at a time.

SLOW IT DOWN, FRAME BY FRAME • Play at 0.25x, 0.5x, or full speed. • Step a single frame at a time and loop the moment that matters. • Frame-accurate scrubbing catches what full speed hides.

DRAW THE DIFFERENCE • Add lines, angles with a live degree readout, and freehand marks. • Annotations stay locked to the video, so they stay aligned as you scrub.

SEE YOUR BODY IN MOTION • Toggle an AI body-pose skeleton over each clip. • Pose detection runs entirely on your device using Apple Vision.

PRIVATE BY DESIGN • No account. No cloud. No uploads. • Your videos, annotations, and pose data never leave your iPhone or iPad.

Great for tennis, golf, baseball, lifting, running, and any sport where form matters.
