Support
Swing Ace helps you swing at the same tempo every time and make your swing repeatable, using three tones for start, top and impact. With the Apple Watch app you can find your own tempo from practice swings (Find My Tempo) and check your tempo on every swing (Tempo Check).
See the Guide (with screenshots) for how to use it.

FAQ
Does it play with the silent switch on?
Yes. The tempo tones play even when the silent switch is on. Use the volume buttons to adjust the volume.
Does it keep playing when the screen is locked?
Yes. The tones keep playing through your earphones or speaker with the screen locked. If you set a practice time (5–30 minutes), playback stops then. With the time set to ∞, it stops 60 minutes after it starts so a forgotten loop doesn’t run forever (you can turn this off in the settings, from the gear icon at the top right). It also stops when your earphones are disconnected.
Do I need an Apple Watch?
No. All tempo practice with sound works on iPhone alone. With the Apple Watch app (watchOS 10 or later) you can also measure your own tempo, check your tempo on every swing and feel the tempo as wrist taps.
Which wrist should I wear Apple Watch on?
Right-handed golfers wear it on the left wrist, left-handed golfers on the right. Set Settings → General → Watch Orientation on Apple Watch to match.
Can I measure practice swings?
Yes. Practice swings and real shots both work. Find My Tempo gives a result from 5 swings.
Why is the measured tempo different from what I expected?
Apple Watch measures your wrist movement and calculates the club’s movement from it, so the result may differ slightly from your actual tempo. Wear it on your lead wrist so it isn’t loose, and check that Settings → General → Watch Orientation on Apple Watch matches the wrist you wear it on. Find My Tempo gives a steadier result the more you swing.
Does measuring on Apple Watch record a workout?
No. While measuring, the app runs as a golf workout so it can keep reading the sensors, but nothing is saved to Health.
Can I change the language?
Yes. By default the App follows your iPhone’s language (Japanese or English). You can switch manually from the gear icon at the top right.
