Precision golf technology

See the shot. Trust the number.

Perret Labs builds precision golf technology for golfers who want the real number. Our first product, Contrail, traces your real shots across a real course.

Every shot leaves a line. We build tools that show you where it went, and how sure we are.

Products

Built for the course, not just the range.

Contrail is our first product. It won’t be our last.

Contrail

Every shot leaves a line.

Hit a real shot on a real course and watch it fly: a broadcast-style tracer across a 3D satellite view of the hole, landing where your ball came down. Then the numbers: carry, total, ball speed, curve and more. Shot tracing works with Garmin Approach R10. No launch monitor? GPS mode measures each shot from your iPhone.

Why we build

Honest numbers, beautifully shown.

  1. Accuracy you can trust

    We show you how sure we are. GPS measurements carry their ± margin, estimates are labeled as estimates, and nothing is quietly guessed.

  2. Privacy by default

    No ads, no tracking, no analytics SDKs. Your shots are yours to export or delete whenever you like.

  3. Built with craft

    Made by golfers, for golfers. We sweat the details, from the arc of a tracer to the spacing on a scorecard, because that’s what makes a tool feel right.

About

A small lab with a long game.

Perret Labs was founded by Cameron Perret in Virginia to build golf technology that’s precise, private and a pleasure to use.

“Perret” comes from Pierre: little stone. A golf ball is a little stone too, and we care most about where it comes to rest.
