Putt Break requires an iPhone with a LiDAR sensor. That means:

• iPhone 12 Pro / 12 Pro Max
• iPhone 13 Pro / 13 Pro Max
• iPhone 14 Pro / 14 Pro Max
• iPhone 15 Pro / 15 Pro Max
• iPhone 16 Pro / 16 Pro Max
• iPhone 17 Pro / 17 Pro Max

It will not work on non-Pro iPhones (iPhone 14, 15, 16, etc.) or older devices, since they lack the LiDAR sensor required for accurate ground measurement.

Under good conditions (overcast or shaded, smooth turf, phone held steady), readings are typically accurate to within ±0.3% slope. In challenging conditions like direct midday sun on light-colored grass, accuracy may drop to ±0.5–1%.

Treat readings as directional truth — reliable for "this green slopes 2% to the right," less reliable for "this green slopes 1.7% versus 2.1%." Always cross-check against your own eyes.

Three common causes:

• Direct bright sunlight on the ground reduces LiDAR accuracy. Try shading the phone with your body or your cap.
• Phone moving too much — hold steady for 1–2 seconds while readings stabilize.
• Surface too close or too far — LiDAR works best between 0.5m and 2m. Adjust your phone height.

If the confidence dots never turn green even in shade, your reading is genuinely uncertain and shouldn't be trusted.

Photos access is turned off. To fix:

1. Open the iPhone Settings app
2. Privacy & Security → Photos
3. Find Putt Break in the list
4. Set it to Add Photos Only

If Putt Break doesn't appear in that list at all, the permission dialog never fired. Delete the app and reinstall — the permission will be requested fresh on first capture.

No. Putt Break is intended for practice rounds and learning only. Rule 4.3a of the Rules of Golf prohibits electronic devices that measure slope or other conditions affecting play during a stipulated round.

Always check your specific competition's rules. Some clubs ban these tools even in casual rounds.

The F reticle is the far point for measuring uphill/downhill slope. It marks "where the hole is" relative to your stance. The app measures elevation change between the midpoint of your L/R reticles and the F reticle's position.

To drag it: touch and hold the F reticle (or anywhere within about 60 pixels of it), then slide your finger up or down. The reticle stays on the centerline. Release to save its new position — Putt Break remembers it for next time.

Narrow stance places the L and R reticles about 30 cm apart — toe-to-toe distance. More local, less precise on subtle slopes.

Wide stance spreads them about 60 cm apart — feet-shoulder-width. Better for measuring subtle slopes (the longer baseline reduces noise) but covers more ground than your immediate stance.

For most reads on a flat-ish green, wide stance gives you a slightly more reliable number.

Real-time AR with LiDAR is power-hungry. To extend battery life:

• Close the app between greens — swipe up from the home bar, flick the app away. Reopens fast.
• Reduce screen brightness slightly when readings don't need to be glanceable from a distance.
• Keep your phone out of direct sun when stowed — heat throttles performance and accelerates drain.

Putt Break is a measurement tool, not an aiming system. To predict where the ball will end up, the app would need to know your putter speed, the green's stimpmeter rating, the grain direction, your stroke tendencies — none of which it can measure.

The app honestly tells you the slope. You translate that into a putt using your own feel and experience. That's by design.

Technically yes, but the readings are mostly meaningless. LiDAR struggles with reflective floors (polished hardwood, tile, glass) and very dark surfaces. For testing the app, carpeted rooms work reasonably well — try a slope reading on a known-flat carpet vs. a doorstep ramp to calibrate your expectations.
