Hit a bad shot? Get instant AI coaching with Apple Watch. The Golf Mentor isn't just a GPS rangefinder — it's an AI golf coach. As you play and practice, your Apple Watch and iPhone quietly capture the shape of every full swing, turning real motion data into plain-English feedback on tempo, rotation, and impact. It works just as well at the range. Set a goal, hit balls, and get the same real-time feedback — including spoken stats and on-wrist thumbs up/down rating — so you can build the swing before you take it to the course. GPS DISTANCES, ON YOUR PHONE OR WATCH Know the distance to the green before you pick a club — on your phone, or a glance at your wrist without breaking stride. EVERY FULL SWING, CAPTURED AUTOMATICALLY Your watch and phone quietly capture the shape of every full swing you make, on the course or at the range. INSTANT AI COACHING Tap Analyze Swing for real coaching feedback on tempo, rotation, and impact — not just a chart of numbers to interpret yourself. RATE YOUR OWN SWINGS, RIGHT ON YOUR WRIST Set a goal, then thumbs up a swing that hits it or thumbs down a genuinely bad one — no phone, no app to open. SPOKEN FEEDBACK AT THE RANGE With sound on, get spoken feedback after every practice swing — like "Tempo 2.3" — so you can check it against your aim without looking down. A RECAP THAT TELLS YOU WHAT TO WORK ON See the shot-by-shot path of every hole, and a practice recap that shows what worked, what didn't, and what's next. Signing up gets you a 21 day free trial.
