ZeroBreak is a science-based putting tool that tells you exactly where to aim and how far to take your putter back — for every putt, on any green. HOW IT WORKS Based on vector putting geometry, ZeroBreak calculates the Zero Break Line (ZBL) — the true aim point that accounts for slope, green speed, and distance. Instead of guessing, you get a precise aim point in inches and a personalized backstroke length for your exact pace. CLOCK FACE AIM Read break the way caddies do. Tap the clock face to set the slope direction — ZeroBreak does the math and shows you the aim point, whether that's the center of the cup, an edge, or inches outside. YOUR STROKE, CALIBRATED Calibrate once by hitting a test putt at a known distance. ZeroBreak learns your personal distance factor and calculates the right backstroke length for every distance from 5 to 100 feet — referenced to your trail foot so you always have a consistent guide. GREEN SPEED BUILT IN Adjust for course conditions with the Stimpmeter slider. Whether greens are running 8 or 12, your aim and speed recommendations update instantly. TRACK YOUR PROGRESS Play a full round with Live Round mode — log putts hole by hole as you go, either with a quick count tap or with full break and distance detail straight from the clock face. After your round, ZeroBreak shows you putts per round, 1-putt %, 3-putt %, make percentage by distance, miss tendency, and a hole-by-hole breakdown so you know exactly where strokes are being lost. No rangefinder needed. No complicated setup. Just better putting.

GreenReader allows visually impaired golfers to place their phone on the green, press a button, and get a read of the terrain for their putt. This will inform you if the putt is uphill or downhill as well as if it is breaking left or breaking right. Given the distance of the putt, our app can also provide a predicated aim point left or right of the hole; for example, 2 cups left of the hole.
