Measure and train your golf tempo with Apple Watch by TrackMyGolf, Free!Back in June 2015 at Apple's developer conference, Apple announced the Ping tempo app which uses the watch's accelerometer to measure tempo. Like many golfers, we have been waiting for this app for a long time. We are finally fed up with waiting and decide to develop it ourselves. This app uses your Apple Watch's accelerometer 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 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.Note 1: Raise wrist to turn on Apple Watch screen before swinging. There is a limited time after the screen goes off that we can still observe a golf swing. It is a platform limitation.Note 2: If no swing is detected for any reason, right after the swing, force touch on watch, then click "log" manual button. The sensor output will be logged on our server. Then email us firstname.lastname@example.org, so that we can take a look.
