DeepGolf Rhythm: Swing Tempo

Train your swing tempo with your Apple Watch. DeepGolf Rhythmus measures backswing and downswing separately on every swing and tells you right away whether you hit your target. The metronome gives you the beat. Apple Watch required. YOUR SWING HAS TWO TIMES Tempo is the sum of both phases, rhythm is their ratio. Both can look right while each phase is off. Example: 1.20 s at 3:1 looks fine. Yet the backswing was 0.12 s too short and the downswing 0.12 s too long. Two errors cancel out. That is why DeepGolf Rhythmus measures two numbers instead of one and judges each on its own. TRAIN WITH THE METRONOME The metronome makes your target rhythm audible: one click at the start, one at the top, one at impact. You swing to the beat, your watch measures whether you really hit it. You build a feel for your tempo and check it with real numbers at the same time. Once the beat is in your head, turn the metronome off and see whether your tempo holds without it. HOW IT WORKS 1. Choose your target: total time and ratio, for example 1.20 s at 3:1. That gives a 0.90 s backswing and a 0.30 s downswing. 2. Start a session on your watch, switch the metronome on if you like and swing as usual. 3. After every swing your watch shows both times, the ratio and a clear sentence such as "Backswing too short". ON YOUR APPLE WATCH • Backswing and downswing in seconds • Ratio and total time • Feedback in one sentence instead of a score ON YOUR IPHONE • Set your target, switch the metronome on and off • Your latest swings against the target zone • A summary of every session: average rhythm, tempo, consistency, hit rate and most frequent error • A backswing-to-downswing chart that shows where your swings land • History across all sessions with mean and spread HOW IT MEASURES Your Apple Watch samples the motion of your wrist at 100 Hz, every 10 milliseconds. Backswing and downswing are detected individually and compared with your target. The tolerance is 8 % of the target value, at least 24 ms. You need no camera and no extra sensor. Put on your watch and start. WHO IT IS FOR Golfers who work on tempo and rhythm and want to know for sure whether their swing hits the beat. WHAT IT IS NOT DeepGolf Rhythmus is not a launch monitor and not a video analysis tool. It measures two times and tells you whether they are on target. REQUIREMENTS Apple Watch and iPhone.
