SwingShadow

Import a tennis video shot from behind the player. SwingShadow analyzes it on your iPhone and marks forehands, backhands, slices and serves on the timeline. Tap a mark to play that stroke.

DETECTION • SwingShadow colors each stroke by type and groups the video into the stretches where you were hitting • Your library shows a count of each stroke type for every video • Turn on the skeleton overlay to check your body position through the swing • Relabel any stroke SwingShadow got wrong

SPLIT-SCREEN COMPARE • Play two strokes side by side, lined up at contact, and slow both to 0.5× or 0.25× • Put today's forehand next to last month's and compare your take-back height and contact point • Import a pro match filmed from behind the baseline, and once SwingShadow analyzes it, you can set a pro's forehand next to yours

HIGHLIGHT REELS • Pick the strokes you want, save them to Photos as one video, and send it to your hitting partner or coach • Exports have no watermark unless you turn it on in Settings

PRIVACY • SwingShadow analyzes your videos on your iPhone, works offline, and needs no account • Your videos stay on your phone. When you correct a label, you can choose to share that one stroke to help improve detection, and you can delete anything you've shared from Settings

HOW TO FILM Set your phone at court level behind the baseline, facing the player's back, with their whole body in frame. SwingShadow doesn't support video filmed from the side or front yet.

Requires iOS 26 or later.
