What is ZeroBreak?
ZeroBreak is a science-based putting tool that uses vector geometry to calculate the precise aim point and backstroke length for every putt on any green. It accounts for slope, green speed, and distance to help golfers improve their game.
How does ZeroBreak help with aiming?
ZeroBreak calculates the Zero Break Line (ZBL), which is the true aim point considering slope, green speed, and distance. You can tap the clock face to set the slope direction, and the app will show you the exact aim point.
How do I calibrate my putting stroke with ZeroBreak?
You calibrate your stroke once by hitting a test putt at a known distance. ZeroBreak learns your personal distance factor and then calculates the correct backstroke length for distances from 5 to 100 feet, referenced to your trail foot.
Can ZeroBreak adjust for different green speeds?
