The launch monitor
you already own

01Launch monitor

Ball speed and launch, shot by shot

Set your phone behind you and swing. The camera reads your swing, and when it can see the ball clearly it tracks it off the club, so every shot comes back with ball speed, launch, and distance.

Ball speed and launch angle
Carry, total, and side distance
Without a ball, the shot is estimated from your swing
Ball tracking is still in beta

How it works

Three steps to your first round

1
Set up
Stand your phone about 3 m behind you on the target line, with the ball and your whole body in view.
2
Hit
Use a real ball or just make a practice swing. The camera reads your swing, and the ball’s launch when there is one.
3
Play and review
Check your numbers and watch the shot play out. You can save any camera swing as a swing report.

Ball numbers are estimates from the camera and are less precise than a dedicated launch monitor. Without a ball, each shot is estimated from your swing.

Questions

Good to know

Do I need any hardware?+

No, just your phone. A small tripod helps, but anything you can lean it against will do.

How accurate is the ball flight?+

With a ball in view, the camera measures ball speed and launch, though less precisely than a dedicated launch monitor. Without a ball, the shot is estimated from your swing.

How does putting work?+

Putting is automatic for now. Once your ball stops on the green, two putts are added to your score.

Where can I swing?+

Anywhere with at least 2 m of clear space around you and the club. Indoors, make a slow swing first to check the ceiling, and use a short club, a swing trainer, or a foam ball.

Is my video uploaded?+

No, your video stays on your device. Your account keeps your scores and rounds, along with the body-position data used for replays.

Which phones does it work on?+

It works on recent iPhones and Android phones in Safari or Chrome, and on iPad as well.

Can I cancel Pro anytime?+

Yes. Cancel in Account & settings and you keep Pro until the end of the period you’ve paid for.
