About
Same tempo, every swing: make your swing repeatable.
Swing Ace trains your body to keep the tempo with three tones for start, top and impact. With Apple Watch you can also find your own tempo from practice swings and check your tempo on every swing.
THREE TONES TO GROOVE YOUR TEMPO
The tones follow the length of your backswing and downswing, at exact intervals. They are scheduled ahead, so the rhythm stays exact even when looping.
THE 3:1 TEMPO COMMON AMONG PROS
Five presets from 18/6 to 30/10, based on the 3:1 backswing-to-downswing ratio known from analysis of tour pros’ swings. There are 2:1 presets for chipping too (14/7 to 20/10).
YOUR OWN TEMPO, ONE FOR EACH CLUB
Fine-tune in 0.01-second steps, then name and save a tempo for your driver, irons and wedges. Recall it with one tap.
PRACTICE AS USUAL, FINISH IN SILENCE
• Keeps playing through earphones or the speaker with the screen locked, even in silent mode
• Set a practice time (5–30 minutes). Turn on Fade out and the tones get quieter over the last 2 minutes, so you learn to keep the same tempo without them
• With no time set, it stops after 60 minutes so a forgotten loop never runs forever (you can turn this off)
• Stops when your earphones are disconnected
CHECK EVERY SWING ON YOUR WRIST (Apple Watch with watchOS 10 or later)
• Find My Tempo: swing 5 to 10 times to learn your own tempo (backswing and downswing in seconds, and how steady you are). Add it to your presets on iPhone and practice with it right away
• Tempo Check: each swing is graded Perfect, Good or Off against your target, with what was off (such as a fast backswing). The tempo playing on iPhone becomes the target automatically
• Haptic Practice: feel the tempo as taps on your wrist
• Look back on your Apple Watch records by day on iPhone
• At home or at the range. No special gear needed
While measuring, the Apple Watch app runs as a golf workout so it can keep reading the sensors. Nothing is saved to Health.
NO WATCH? NO PROBLEM
All tempo practice with sound works on iPhone alone.
