Precision ball tracking
Stand your phone behind the ball. ShotArc follows it off the face, traces the line, and reads back ball speed, launch, carry and the quality of the strike.
No gadgets
The measurement most players never had access to, from the phone already in your pocket — on the range at dawn, in the bay in winter, or standing on your own back garden.
How it plays
On the ground or a tripod, a couple of paces behind the ball and down the target line. Nothing to pair, nothing to charge.
ShotArc finds the ball at rest on the grass, then follows it into flight and draws the arc as it climbs — indoors into a net, or out to the horizon.
Ball speed, launch, start line, carry and a score for the strike. On a course, where it comes to rest and your standing against par.
Afterwards
Each session syncs to a private dashboard: the shape of every shot down each hole, its flight in profile, your longest of the day and your score. Yours to revisit.
A sample round. Your dashboard opens with the Members link.
