Green Reader: Putt Break

Read the break on any putt — then log how it dropped. Green Reader turns your phone's motion sensor into a slope meter for the putting green: lay it flat near your line and instantly see how the surface tilts, which way the ball will break, and where to aim.

WHAT YOU GET

• Slope reading — the grade of the green shown as a percent and in degrees, with an arrow pointing downhill, the way the ball wants to roll. • Break & aim point — the app splits the slope into the part along your line and the part across it, then turns the cross-slope into a clear "aim this many inches left or right of the hole" read. • Uphill / downhill pace — know when a putt plays uphill and needs a firmer stroke, or downhill and needs an easy touch. • Distance aware — longer putts break more, so feed in the distance for a sharper read. • Green speed (Stimp) — faster greens break more; set the Stimp and the aim adjusts. Leave it at 10 for an average green. • Simple putt line — point the top of your phone at the hole and nudge the on-screen line. No compass needed.

PUTT LOG & MAKE-PERCENTAGE STATS

Reading the green is half the game; the other half is knowing where you actually miss. Log each putt in a tap — its distance, the way it broke, and whether it dropped — and Green Reader keeps your overall make percentage plus a make-rate breakdown by distance bucket. See at a glance that your 3-footers are money but your 15-to-20-footers need work, then practice the range that matters. A recent-putts list lets you review and delete entries, all stored on your device.

HOW TO USE IT

Walk your line, rest the phone flat on the green, and read the slope. Aim to the high side — the ball always breaks toward the low side. More cross-slope or a longer putt means more break. After the stroke, log the result and build your make-percentage over time.

FOR GOLFERS

Weekend players learning to read greens, practice-green sessions, and anyone who wants to understand why their putts keep sliding past the hole.

A NOTE ON ACCURACY

This is a practice aid. The slope comes from your phone's accelerometer and is approximate, and the break is a modeled estimate, not a measurement. Grain, moisture, footprints and multiple slopes between ball and hole all matter. Read the whole line and trust your own eyes.
