PuttArc - AR Putting Analysis

Turn your iPhone into your AR putting coach. Read greens offline, see slopes clearly, and find better putting lines.

PuttArc uses your iPhone's LiDAR sensor, AR, and AI vision technology to scan the green in real time, automatically detect the ball and hole, and overlay a suggested putting line directly onto the real green.

All analysis runs entirely on-device. No internet is required, so PuttArc works even when there's no signal on the course—whether you're practicing on the putting green or using it during casual play.

Key Features

AR Putting Line Generate a suggested putting path based on real-time terrain data and view it directly on the green. See the aim direction, lateral break, and full putt path clearly in AR.

Real-Time Terrain Heatmap Visualize subtle slopes and elevation changes with a color-coded heatmap overlaid on the real green. Adjustable sensitivity helps you inspect terrain changes in more detail.

Automatic Ball and Hole Detection AI automatically detects the positions of the ball and hole as you scan the green. Manual marking is also supported for added flexibility.

Complete Green Reading Data Get detailed read data including uphill/downhill slope, side slope, lateral break, aim point offset, and effective putting distance adjusted for slope.

Green Reading Practice Mode Make your own read first, then compare it with LiDAR-based analysis. A five-dimensional scoring system tracks your progress across distance, effective distance, front/back slope, side slope, and aim point judgment, with trend charts and radar analysis.

Record and Share Record AR putting analysis videos with projected lines and heatmaps, then share them with friends or on social media. You can also generate scorecard-style practice snapshots to show your green-reading performance.

Green Speed Calibration Set the green speed (Stimp 6–14) to match real course conditions, so line and break calculations better reflect actual putting speed.

Supports 22 Languages English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, Spanish, Portuguese, Italian, Dutch, Swedish, Norwegian, Danish, Finnish, Turkish, Thai, Vietnamese, Indonesian, Malay, Hindi, and Filipino.
