PuttLevel: Green Slope

PuttLevel is a focused practice tool for reading a putting surface in two axes. Point the top of your iPhone toward the hole, place it on the surface, and read cross-slope, hole-line slope, total slope, downhill direction, and measurement stability. Calibrate the device before use, hold a stable reading, and record the result of each putt. PuttLevel Pro adds local practice records, make rate by distance, miss distribution, and recent practice trends. PuttLevel does not require an account and does not show ads. Sensor readings and practice records stay on the device. Apple processes purchases, and RevenueCat processes anonymous purchase history for validation, restore, and Pro entitlement access. PuttLevel is a practice aid, not a certified surveying instrument. Check local and competition rules before using it during a round.
