SwingStudio

Your swing. Captured. Analyzed. Perfected.

The app for iPhone, iPad, and Mac that turns every practice session into a coaching session — automatically.

Scroll

Always recording.
Never miss a swing.

A dual-file AVAssetWriter system maintains a rolling ~60-second capture buffer. When a swing is detected, the clip is automatically extracted—no need to hit record. Just swing. Clip duration is configurable from 3 to 45 seconds. And if auto-detection isn't what you want, a "Save Last Swing" button lets you manually grab the most recent clip on demand.

iPhone films.
iPad coaches.

Connect your iPhone as a camera and iPad as a studio using peer-to-peer connectivity. Asymmetric discovery means each device knows its role instantly. Video streams in real-time; clips transfer automatically.

Your swing,
found automatically.

Vision pose estimation runs at ~15 frames per second, feeding a heuristic energy detection pipeline. When motion energy crosses the threshold, your swing is detected and a clip is extracted—automatically, every time. Choose from swing alerts—an audible chime or a camera flash—so you know it was captured without ever looking at the screen.

Draw on your swing.
See what matters.

Lines, circles, boxes, angle measurements—all in multiple colors with three line thickness options and full undo/redo. Annotations overlay your video so you can mark positions, trace paths, and measure angles frame by frame. When you export, annotations are burned directly into the video frames—your markup travels with the clip.

Two swings. One screen.
Every difference visible.

Load any two clips into a two-up comparison view with independent playback controls. Swap panels with a tap to flip your perspective. Share annotation mode across both panels to mark up differences in real time.

Study the swings
you admire.

Import professional swing videos from your Photos library or Files. Tag them, favorite them, and study them alongside your own clips in the comparison view.

Every session.
Organized. Searchable.

An Instagram-style feed of your practice sessions with filter chips, grid and feed view toggle, and date-grouped organization. Search by tags or notes to surface exactly what you need. Import sessions from Photos or Files to consolidate your entire swing library in one place. Find any swing from any session instantly.

Share your progress.
Annotations included.

Export any clip as a video with your annotations composited directly into the frames. Lines, circles, angles—all burned in, frame by frame. Then share via Messages, AirDrop, or save to your camera roll. Your markup travels with the video.

Tag it. Find it.
Instantly.

Add notes to any session or clip with inline #hashtag support. Tags are extracted automatically, deduplicated, and searchable. Start typing a tag and autocomplete suggests matches from your history. Filter your entire library by any tag in seconds.

240 frames per second.
Every micro-movement.

Capture at up to 240fps for frame-by-frame slow motion of your fastest moves. Choose from 240, 120, or 60fps. Pair with configurable video quality—from balanced 720p to maximum 4K detail—and optional compression that runs in the background without interrupting capture.

iPhone. iPad. Mac.
Your swing, everywhere.

SwingStudio runs natively on iPhone, iPad, and Mac. Capture at the range on your iPhone, review on your iPad courtside, then take your clips home and analyze every frame on the big screen. On Mac, dive deep into offline analysis—annotations, comparisons, and frame-by-frame review on a display built for detail.
