SwingRatio: Swing TempoSupport
SwingRatio is designed to measure tempo reliably and work easily in your practice routine. If you have questions, run into issues, or want to suggest improvements, we're here to help.
Where should I put my iPhone?
Put your iPhone in your front trouser pocket, vertical orientation. The app senses the motion of your hip rotation. The app will tell you when it's ready to measure.
How accurate is SwingRatio?
SwingRatio measures backswing and downswing duration to within ±5% for about 96% of swings. This is a tool for measuring time, not for diagnosing your swing. See the Help section in the app for details.
What does the confidence score mean?
Confidence measures how clear your swing was to the sensor. It's based on the sharpness of your peak and the steadiness of your setup. If it's low, take another swing — the sensor needs a crisp motion to work well.
Can I measure with my Apple Watch?
Yes. If you're wearing an Apple Watch on your dominant wrist, SwingRatio can measure from there instead. Settings let you choose automatic, iPhone-only, or Watch-only.
Is there coaching or advice built in?
No. SwingRatio measures time. It does not coach, diagnose, or tell you what your swing should be. It shows you the number and lets you decide what to work on.
