Swing Ace
Just swing to three tones. At home or at the range.


How it works
The gaps between the tones teach your body how long your backswing and downswing take.
Swing with the tones, and you swing at the same tempo every time.
From analysis of tour pros’ swings
Backswing 3 : downswing 1. Swing Ace’s presets use this 3:1 ratio, at five speeds. Not sure? Start with 27/9.
My Presets
Fine-tune your backswing and downswing with the sliders in 0.01 s steps. Name it and save it, and it’s one tap away next time.


In your practice
Apple Watch
Find My Tempo
Wear it and make a few practice swings to find your own tempo. Swings far off from the rest are left out.
Find My Tempo
The result goes to iPhone. Add it to My Presets and practice to the tones of your own tempo.
Tempo Check
Each swing is graded Perfect or Good, and when it’s off, you see what was off, such as “Backswing fast”.
Tempo Check
Open Tempo Check while Swing Ace plays on iPhone, and the tempo playing becomes your target automatically.
Haptic Practice
Taps on your wrist at start, top and impact let you practice the tempo without making a sound.





Tempos measured on Apple Watch are estimates calculated from your wrist movement. The Apple Watch app requires watchOS 10 or later.
Records
