What ships today
Three engines, one app.
Everything below is in the App Store build right now. What isn’t, we list separately — see the roadmap.
Launch Monitor
Set your iPhone down and hit. The camera captures at 240 fps, the model runs on-device, and you get ball flight, result, and club delivery — no radar unit, no sensors, no calibration.

The same capture reads your body. Fault detection with the measurement behind it, a plain-language debrief, your P1–P10 positions, and the kinematic sequence — hips, chest, hands.
Learn more → Available nowThe Greens
LiDAR maps the corridor between your ball and the cup, then draws the line on the surface. Pick your speed, hit it, and see your roll against the perfect one.
Learn more →Every shot
13 metrics, including club delivery.
Most phone apps stop at ball speed and carry. LiPAR reads what the club did to produce them — path, face, and attack angle included.

Scored, not just measured
Two indices that get sharper as you play.
LiPAR Index
61.6 ± 25.0
Your whole bag against a tour swing, 0–100. The band is the honest part: with three swings it’s wide, and it narrows every time you hit. Filter it by driver, woods, irons, or wedges.
Swing Coaching →LiPAR Putting Index
97 LPI
How close your roll was to the perfect one — line and pace, measured against the ideal. A lipped-out putt struck perfectly still scores like the good putt it was.

About
Launch monitors were invented decades ago.
They still cost thousands, still need their own case, and still have to be set up before you can hit a ball. Meanwhile the phone in your pocket ships with a high-speed camera and a depth sensor — most of the hardware problem, already solved, already paid for.
The remaining problem was software, and it was not a small one. Reading spin off a golf ball at 240 fps and inferring what the club did to produce it is genuinely hard, and it had to run on the phone rather than in a data center — partly for privacy, mostly because a round trip to a server costs more time than the whole computation does. That took a long time to get right.
Accuracy claims are cheap, so we tested ours in the open. In live side-by-side testing against a professional-grade launch monitor, LiPAR matched ball speed, carry and spin to within 2%. Not in a lab — head to head, shot after shot, on camera. When a number here is soft, the app tells you: the LiPAR Index carries a confidence band that stays wide until the model has seen enough of your swing to narrow it.
The models learned from real golfers before that was possible. Our beta users hit the shots that trained them, in their own garages and bays, against their own nets — which is why the app works in the places people actually practice, rather than only in the places a demo gets filmed.
