Read the manifestoThe hardest shot in golf
Reading a green is the hardest shot in golf.
~40% of strokes are putts — and it's the one shot where everyone, from the Tour to Sunday morning, is still guessing.
Lasers and lines
They help you groove a straight stroke — but say nothing about this green, here, right now.
Five-figure systems
The most capable systems cost five figures and need their own hardware — nothing you'd carry in your pocket.
How it works
Point. Scan. Read the line.
Four steps run entirely on the phone — from raw LiDAR to a putting line drawn over the green in AR.
Scan
iPhone LiDAR captures the green in seconds — dense, precise, anchored to the real world.
Fuse
Frames fuse into a single surface grid — slope, fall lines, and micro-contours, with per-cell confidence.
Solve
A physics-faithful solver finds the optimal aim and pace given gravity, friction, and green speed.
Render
The line draws over the green in AR — and the session saves locally for later review.
Designed for iPhone 12 Pro and later (Pro series). Verified on iPhone 16 Pro and later; older Pro devices in validation.
Technology & moat
Built to refuse a wrong answer.
The wedge is reading any real green on hardware you already own. The moat is refusing to guess when it shouldn't.
Validated in real time.
A multi-stage confidence system validates each reading in real time — if the data isn't clean enough to trust, BullzEye says rescan, not a wrong line.
Pinned to the rulebook.
Anchored to regulation golf geometry and published putting physics. Verified against a known physical world.

The most decisive stroke in golf. The most under-instrumented.
