Swing Analyzer
Every swing, found for you
Prop up your phone and hit balls. Swing Analyzer hears each strike and cuts that swing out of the recording, so there is nothing to tap between shots and a practice swing is kept apart from a real one.
See what your swing actually does.
Film a practice session on your phone or any camera. Swing Analyzer finds every swing, measures it, and shows you what changed from one to the next.
Download for Mac Join the iPhone beta
Free. The Mac app needs macOS 26 on Apple silicon; the iPhone beta needs iOS 26 and Apple's TestFlight app.
Your positions and tempo, measured
It tracks your body through every swing and marks the moments coaches talk about: address, the top, impact and the finish. It measures your tempo, and lines today's swings up against last week's so you can see what really changed.
Coaching that points at the frame
Ask about a swing and get feedback tied to the moment it happens, with the guide lines drawn on, instead of advice about a feeling. Optional, and it uses your own Anthropic API key.
See a whole session
A short film of a real practice session is on its way: the phone on a tripod, every swing found as it happens, then each one reviewed with its positions and tempo.

Wherever you practise
At the range
A phone on a small tripod behind you is enough. Every ball you hit becomes a swing you can step through frame by frame.
At home, into a net
It listens for the strike, not the ball flight, so a net in the garage or garden works too.
In a simulator bay
A bonus, not a requirement: when the launch monitor's numbers are on screen, it reads them and puts them beside the swing.

The iPhone app films a session, finds each swing and measures it with no Mac in the room. Install TestFlight, then open the link on your iPhone.
Your footage stays yours
Video is stored and measured on your own devices. There is no account and no upload. If you ask for coaching, a few still frames and the measurements go to Anthropic's API under your own key, never the video. Privacy policy
