An illustrative swing at a 3:1 tempo. The line traces the lead wrist.

No clip-on sensor. No camera on a tripod. Your iPhone goes in your pocket, your AirPods in your ears, your Apple Watch on your wrist, and you hit balls.

Built on the devices you already carry.

Three devices work together, each measuring the part of the swing it’s closest to.

The Striped Practice screen while recording: 7-iron, 2 minutes 13 seconds elapsed, 6 swings detected, and the latest swings at 2.8, 2.6 and 3.1 to 1. The Striped watch app recording for 2 minutes 13 seconds, with a Stop button.

  • A metronome for your swing

    Three tones mark takeaway, top and impact. Four full-swing paces at 3:1, and 2:1 for the short game and putting.

  • Your tempo, spoken

    After each swing you hear a soft chime, then your backswing-to-downswing ratio read out.

  • As much as you want to hear

    Choose what gets read out, or turn the voice off and keep just the chime.

Every swing, measured.

After each session, the report breaks down every swing: your tempo first, then how your hips, head, hands and wrists moved.

What do I need to use Striped?

Striped is built around three devices working together: an iPhone running iOS 17 or later in your front pocket, motion-capable AirPods, and an Apple Watch running watchOS 10 or later. You sign in with Apple to use the app.

What does Striped measure?

The tempo of every swing: backswing time, downswing time and their ratio. Alongside it, your hip turn, head movement, swing plane and hand path, and wrist speed, plus the tempo of your chips, pitches and putts.

Do I have to look at my phone while I practice?

No. Lock the screen and keep it in your pocket. The metronome and your tempo come through your AirPods, and you can stop the session from iPhone or Apple Watch.

Where are my recordings stored?

On your iPhone. Private cloud backup is optional and stays off until you turn it on, and video and audio are only uploaded if you include them for a session. The privacy policy has the details.

Do I need an account?

Yes. You sign in with Apple, so there’s no new password to remember.
