How it works

Swing to three tones.
That’s it.

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

The 3:1 tempo common among pros.

3:1

Backswing 3 : downswing 1. Swing Ace’s presets use this 3:1 ratio, at five speeds. Not sure? Start with 27/9.

The result goes to iPhone. Add it to My Presets and practice to the tones of your own tempo.

Tempo Check

Compare every swing with a target.

Each swing is graded Perfect or Good, and when it’s off, you see what was off, such as “Backswing fast”.

Tempo Check

Playing on iPhone? That’s the target.

Open Tempo Check while Swing Ace plays on iPhone, and the tempo playing becomes your target automatically.

Haptic Practice

Feel the tempo on your wrist.

Taps on your wrist at start, top and impact let you practice the tempo without making a sound.
