Build your confidence in your green reading and putting, take advantage of the great shots you hit on the green, and create breakthroughs in your game! FEATURES • *NEW Course Mode - Sharpen your visualization skills with our new revolutionary, patent pending, virtual ball rolling simulator that displays 3D greens from any course in our database in life-sized form in augmented reality, allowing you to see how balls will break as if you are standing right there on the green! You can set the hole location anywhere on the green, see how many paces the pin is from the edges of the green, roll virtual balls on different green speeds, and experience how they interact with the hole and/or flagstick. • **NEW and IMPROVED Slopegraide AR - Quickly roll virtual balls and capture slope measurements with a single tap and see exactly how your putt will break in augmented reality! • *NEW 3D Putt Model - Displays a 3D animated rolling model of any putt inside 30 feet in augmented reality, giving you a 1st person point-of-view (POV) angle showing you the rolling arc of your putt and distance timelines that help you visualize the rolling speed of putts. • *Roll Maps - Our popular color-coded charts that trains your distance control and feel on the greens quickly. Contains both a Training Mode and Tournament Mode that conforms to the Rules of Golf. • *Putting Stroke Model - Displays an animated visual model of an optimal putting stroke for any putt inside 100 feet, complementing reads of your putts with speed control at the press of a button. • *Life-Sized Putting Stroke Model (iPads only) - Our putting stroke model with the golf ball and putter enlarged to their life size, so you can follow the putter being animated on the screen, giving you an accelerated path to hitting putts at optimal speed! • *Classic Mode - Displays recommended start lines based on conservative or aggressive putting styles. This feature accommodates players that prefer to hit putts at dead weight and players that like to aggressively run putts past the hole. • Four Display Modes to accommodate any green reading style: - Slope Percentage - *Recommended start Lines displayed in inches or feet (Imperial) - *Recommended start Lines displayed in centimeters or meters (Metric) - Slope Degrees • *Displays Backstroke Length that tells you how far back to take your putter to create optimal speed of your putts every single time • *Customizable Putt Tempo - Find the putting stroke pace (46 bpm to 85 bpm) that works best for you! • *Our Slopegraide smart ball marker can be used with your Apple Watch without having your iPhone nearby! • *Uphill / Downhill support up to 1 foot each way • *Supports green speeds between 6 and 15 on the Stimpmeter (incremented by 0.5) • Trains the four most important elements; green reading, start line, speed control, and visualization; improving your putting in just a few minutes! *An annual Slopegraide Premium in-app subscription are required for full functionality of this app. Please go to http://www.slopegraide.com to purchase your ball marker. ** Slopegraide AR requires an annual Slopegraide Premium in-app subscription and requires LiDAR that is supported by only the following devices: iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15 Pro, iPhone 15 Pro Max, iPad Pro devices from 2020 and later.

PuttArc

Features
Read full description

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. Why PuttArc • Fully offline — works even when there's no signal on the course • AR overlays directly on the real green, not just a flat diagram • Real-time LiDAR scanning makes slopes and contours easier to understand • Built for both practice and on-course use, helping you improve your green reading over time Requirements • A LiDAR-equipped iPhone (iPhone 12 Pro and later Pro / Pro Max models) • iOS 16.0 or later Important PuttArc is a practice and training tool. Under USGA / R&A rules, the use of electronic devices for stroke assistance is not permitted during official golf competitions.
