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.

Read greens like a tour caddie. ProSide uses your iPhone Pro's LiDAR scanner to map any green, calculate the break, and show you exactly where to aim. Stop guessing. Start making putts. HOW IT WORKS Scan the green. Point your iPhone Pro at the green around your ball and the hole. LiDAR captures slope and elevation in seconds. See the break. ProSide turns the scan into a smooth elevation model and works out how the ball will roll. You get the predicted path, the slope direction, and a clear aim point. Pick your view. Read the green in live AR right where you're standing, or switch to a 2D contour map or a full 3D surface model. Same accurate read, three ways to look at it. Practice and improve. Make your own read first, then compare it to what ProSide calculated. Over time you'll see whether you struggle with downhill putts, sidehill putts, or longer distances — and you can practice exactly where you need to. WHY PROSIDE Built around LiDAR. ProSide was designed from day one for the LiDAR scanner in iPhone Pro and Pro Max. The result is precise, repeatable reads — scan the same putt twice and you get the same answer. No extra hardware. No ball markers, no sensors, nothing to charge or lose. Just your phone. A practice tool, not a tournament aid. ProSide is built for the practice green and training sessions. Always check the rules for your course, league, or tournament before using any electronic aid during a competitive round. REFERRAL PROGRAM Share your unique code from the in-app partner dashboard.

Verdict
The clearest difference is rating: ProSide at 4.7 against Slopegraide's 4.2. ProSide also leads on ads (none vs shown). Slopegraide's advantage is ratings volume (20 vs 3) and device support (3 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
