For golfers on their own
Range time that adds up to something.
Most of us practice without knowing whether anything is changing. Mastery gives you one thing to work on and then tells you, from your own video, whether it moved.
One thing at a time
No list of faults. The single change most likely to help your striking right now.
Your swings, kept
Every swing you send stays in your own private history. Delete any of it whenever you like.
Proof, not vibes
Film again and Mastery compares you with you — and says plainly if nothing changed.
