ZeroBreak vs Golf Slope Level Green Reader

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.

Golf Slope Level: Green Reader turns your iPhone into two practice-green training tools: a precision slope level and a walk-off distance measurer. READ THE SLOPE Lay the phone flat between your feet, bottom edge at one shoe and top edge at the other. The on-screen vial runs along exactly the line it is measuring, and the reading is the tilt across your stance in percent, to two decimal places. It measures against gravity, so there is nothing to calibrate and nothing to zero. A second view shows the full fall line: total slope, the angle, and the clock direction a ball would roll from that spot. If the hill does not run straight down your stance, the app tells you how far off you are so you can find the true fall line by turning the phone. TRAIN YOUR FEET Reading a green by feel is a trainable skill, and the way you train it is guess and check. Stand across the slope, commit to a number, then set the phone down and see how close you were. The app scores every read and keeps your streak. MEASURE THE DISTANCE Stand at the ball, tap start, walk to the hole, tap again. You get feet, metres and pace count, converted through a stride you calibrate once by walking a known distance. In Train mode you call the length before you walk it, and the app scores the miss. SEE YOURSELF IMPROVE Every rep is logged on device. Charts show your accuracy over time, your hit rate inside your own tolerance, your best run, and most usefully whether you systematically read slopes high or low and call putts long or short. Accuracy is broken out by steepness so you can find the band that catches you out. BUILT-IN DRILLS Blind walks, one-foot balance on a slope, circling the hole to find the fall line, marked reference slopes at 1% through 4%, and the two-way check. PRIVACY Everything stays on your phone. No account, no tracking, no data collected. Motion access is used only to read the slope and count your paces. Note: electronic slope-measuring aids are for practice. Check the Rules of Golf before using anything like this during a round.
