HOW THE MAPS ARE MADE

Measured, not guessed.

Most golf apps trace a satellite photo. We build each hole from open survey data, then check it against the club's card.

QUESTIONS

Good to know

Which courses are in it?
We're starting in Ohio and adding courses as each one is built and checked. Courses with a verified club card are marked ready; others are labeled unverified until a golfer who knows them confirms the map. You can request a course from inside the app.
Do I need an Apple Watch?
No. The iPhone app does maps, distances, logging and stats on its own. The watch adds automatic shot detection and a phone-free round.
Is my handicap official?
No. The app estimates an index from your best 8 of your last 20 differentials, the World Handicap System way. Your official index still comes from your golf association.
What does it cost?
The beta is free. Pricing for the App Store release hasn't been set yet.
Where is my data stored?
On your iPhone and Apple Watch. There's no account and nothing is uploaded, unless you choose to send us a bug report or course request. See the privacy policy.
