Your iPhone goes in your pocket, your AirPods in your ears and your Apple Watch on your wrist, and you hit balls. There’s no clip-on sensor or camera on a tripod.
Built on the devices you already carry.
Three devices work together, each measuring the part of the swing it’s closest to.

What do I need to use Striped?
Striped is built around three devices working together. An iPhone running iOS 17 or later goes in your front pocket, motion-capable AirPods go in your ears, and an Apple Watch running watchOS 10 or later goes on your lead wrist. You sign in with Apple to use the app.
What does Striped measure?
The tempo of every swing, which is your 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 included in the free trial and in Striped Premium. It is optional and on until you turn it off. It uploads session data only. Video and audio are uploaded only if you include them when you back up 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.
