Drop strokes without expensive lessons. The Swing Sensei scores your golf swing out of 10 and shows you exactly what to fix — in seconds, on your iPhone.

WHY THE SWING SENSEI IS DIFFERENT
Most AI golf apps upload your video to a cloud server. The Swing Sensei does everything on your phone using on-device CoreML and a custom-trained pose detection model. That means:
- No uploads, ever
- Works at the range, on the course, anywhere — no signal required
- Faster results — typically under 5 seconds per swing
- Total privacy by design — your video never leaves your device
- No hidden cloud fees passed on to you

PRICING
Free: 3 swing analyses per month. Subscription and lifetime options available in the app.

PRIVACY FIRST
The Swing Sensei is one of the only golf apps that processes everything on-device. We never see your video, your swings, your scores, or your data. We can't — by design.

Stop guessing what's wrong with your swing. Start fixing it.
