DuffMate
Golf Shot GPS & Score Tracker
$5.99 · Designed for iPad. Not verified for macOS.
Golf cart doesn't have a GPS with hole display and distances? DuffMate added that screen to the iPhone.
"Was that a 6 or a 7!?" - DuffMate has you covered.
"My cart doesn't have a GPS screen!" - DuffMate has that one covered, too.
DuffMate counts your golf shots. Full swings are detected automatically — so you can keep your focus on your golf round.
Wear your Apple Watch. Swing. DuffMate feels the motion and logs the shot. Tap in your putts and the score is recorded.
Your iPhone stores your stats, replays your round, and now shows a live satellite GPS view of the hole you're playing — or lets you preview any course before you tee off.
WHAT DUFFMATE DOES
• Automatic shot detection — Developed by a fighter aircraft flight control designer with a wife learning the game, the Watch's motion sensors recognize the golf swing and does the counting. Adjustments are made with a quick tap.
• Live GPS on your iPhone — a satellite view of the hole you're playing, front/center/back yardages, and tap-to-measure distance to anywhere on the map. Works for the round in progress or to scout a course ahead of time.
• GPS distance to the green — yardage to the front, middle, and back on every hole. Distance from your last shot is provided, a big help for learning club distances.
• Live wind — speed and direction to the hole on your wrist before you pick a club.
• Putts, your way — tap to log putts separately from your shots. Turn them off if you'd rather not track them.
• Real-time sync — your scorecard and shot history update to your iPhone as you play, hole by hole.
• Scorecard & shot map — after the round, see your full scorecard with saved driving distances on par 4/5's. A satellite map shows where each full shot was taken.
• Stats & personal bests — round history, scoring trends, best rounds, and personal records, all on your phone.
WHAT YOU NEED
An Apple Watch and an iPhone. No extra sensors, no extra gadgets, no subscriptions.
YOUR PRIVACY
Your rounds live on your iPhone and Watch. There are no accounts to create, no data sold, and no tracking. DuffMate reaches out for two things only: weather data for your round, and looking up your course. That's it.
---
DuffMate is made for golfers who want to devote more focus to their round and less focus on counting strokes. And oh by the way - the app has features that the low handicappers depend on.
New: Live GPS — see a satellite view of the hole you're playing right on your iPhone, with distances to the green and the ability to tap anywhere on the map to measure distance.
