See the break before you putt. Green Reader maps the green with LiDAR and shows exactly where to aim. Requires iPhone 12 Pro or a newer Pro model.
Requires an iPhone Pro with LiDAR: iPhone 12 Pro or a newer Pro / Pro Max model.
See every break before you putt. Green Reader turns your iPhone Pro into an augmented-reality green reader. It maps the green with the LiDAR scanner and draws the putt line, the break and the exact point to aim at — right on the real grass.
HOW IT WORKS
1. Mark the ball — point at it and the marker locks on.
2. Mark the hole — the cup is found automatically.
3. Walk the line — the green you cover fills in as you go.
4. Read the putt — see your aim point and how the putt plays.
WHAT YOU SEE
• The ideal putt line, curving with the green
• Where to aim, in centimetres or inches and in cup widths
• Contour lines showing the shape of the green
• Slope arrows showing which way the ball falls
• Distance, plays-like distance, uphill or downhill, and the slope at the hole
MADE FOR REAL GREENS
• Set the green speed (Stimp) and your pace — die it, ideal or firm — and the line updates instantly
• Ball and cup are found automatically with the camera and LiDAR, or place them yourself
• Works on any putting green, indoors or out
• Putts up to 15 m (49 ft), metres or feet
PRIVATE BY DESIGN
Everything is computed on your iPhone. No account, no tracking, nothing uploaded.
