Features

Measure your swing tempo by putting your iPhone in your front pocket. No need to set up equipment or have someone film you.

Take one practice swing and get your backswing-to-downswing ratio immediately. A single swing, one number.

Your tempo is drawn as one bar split in two. The length of each part is the real time it took. The seam is where you reach the top of your swing.

Every saved swing becomes another bar in your log. When seams line up, your tempo is repeating. When they drift, you spot inconsistency at a glance.

Keep separate stacks for driver, iron, wedge, and putter. See how your tempo changes with different clubs.

Set your own target tempo. A line on the result screen shows your goal alongside your measured swing.

The motion sensor reads 200 samples a second to detect three moments: start, top, and impact. Accuracy within ±5% for 96% of swings.

All swings are saved on your iPhone. Nothing is sent to servers, no account needed, no internet required.

Each swing shows a confidence score based on the sharpness of your swing and the stillness of your setup. Retake if needed.
