// How it works

Three taps to a confident read.

Most golfers misread breaks by 30 to 50 percent. Pros use a caddy. Amateurs guess. Breakly closes that gap with the same physics tour caddies use, in your pocket.

01

Stand behind your ball

Pick the line you want to play. Stand behind the ball looking at the hole, the way you would normally read a putt.

02

Measure the slope

Hold your iPhone flat on the green. Breakly reads the slope from your phone's motion sensors. Or enter slope manually if you prefer.

03

Read your aim point

Enter putt length and green speed. Breakly tells you exactly how far outside the cup to aim, in centimeters. No more guessing how much to play.

// What's inside

Built for real greens.

Designed for use on the green, in landscape mode, on the course. Every feature exists because a golfer asked for it.

Slope from sensors

Your iPhone's motion sensors measure slope to 0.1 percent. No external hardware needed.

Stimp 7 to 14

Adjusts for everything from soft member greens to lightning-fast tour conditions.

1 to 20 meters

Works for everything from short tap-ins to long lag putts across the green.

Three palettes

Oak, sage, and slate themes. Pick what reads best in your light, on your eyes.

Sign in with Apple

One tap to sign in. No email, no password, no tracking. Your reads sync across devices.

Landscape mode

Optimized for use on the green. Big numbers, easy taps, designed for sun-bleached screens.

// The science

Built on physics.
Refined with data.

  • 01

    Tour-grade physics model

    RK4 numerical integration of the ball's trajectory across slope and friction, the same approach used in tour caddy systems.

  • 02

    1,750 tour reads

    Calibrated against pro caddy reads at major championship venues. The model knows what a caddy would say.

  • 03

    Hybrid correction layer

    Physics provides the foundation. Empirical data corrects for green-specific quirks like grain and crown effects.

// The maker

Designed in Stockholm.
Built for golfers.

Breakly started where most golf tools start, on the green, three feet from the hole, on a putt that should not have been hard. The break was small. The miss was bigger. The next read was a guess.

There had to be a better way than guessing. The tour has caddies, lasers, AimPoint specialists. The rest of us have eyes and hope. So we built the tool we wanted to use. Physics on the inside. Three taps on the outside. Calibrated against real reads.
