We are finally fed up with waiting and decide to develop it ourselves. This app uses your Apple Watch's accelerometer/gyroscope to measure your tempo. You can compete with others on the longest streak of golf swings with a perfect tempo. The app also offer statistics on percentage of slow, fast, or perfect tempo swings, so you know what to work on. An ideal tempo has 3:1 ratio, meaning your back swing should be 3 times as long as your down swing. If you want to measure your swing tempos (and more) in real games, you can also use our golf GPS + Scorecard app which tracks your swing on the golf course, in addition to telling you GPS distances to 35,000+ golf courses and track your shots automatically. This is designed for Watch OS3, with a much more robust swing detection algorithm. No more limitations on swing detection like in version 1.x. Note: If no swing is detected for any reason, right after the swing, you may be prompted to log the trace. Click log, then email us [email protected] with the time of logging, and we will take a look. ** Watch OS3 is required for this app. If it is not showing on your watch, go to Apple Watch app on Phone, choose "General->Software Update" and follow instructions. ** This app integrates with Apple HealthKit. It records your golf practice session as a golf workout.
