I’ve been a pretty good golfer my whole life, with a handicap as low as a 2. I’ve always considered myself a good green reader. I’ve unlocked so much more with this app. I was recently struggling with speed control and found this app after watching a few videos of Bryson discussing his putting philosophy. I found this app, started working with the roll maps feature, and now I’ve mostly memorized how far to take the putter back for various distances. I now can walk up to a 27 foot putt with 3 inches of downhill and think to myself “I need to take the putter head back about 14 inches, or about 4 inches outside my right foot.” I’ve also recently started using aimpoint, and this app has some great features for how much putts will break. 6 footers feel automatic. It’s incredible! ### 5/5 — Game changer *2023-09-20* Slopegraide and Roll Maps are game changers when it comes to green reading and putt simulation. There isn’t another product that is this accurate and easy to use. ### 5/5 — This app and Roll Maps will change your putting forever. *2022-05-23* I recently heard about this app and Roll Maps a while back ago. I’ve always been a decent putter in golf since I was 4 years old and played in high school. Roll maps and this app had been a game changer for my putting and my pre shot routine. I don’t know where I would be without it. Thank you for creating such an amazing app and Roll Maps to go with it. ### 5/5 — No more guessing how to putt *2022-05-12* I’m new to golf. This app helps me to visualize the putt. There is no guessing where the ball will roll. It helps me practice confidently and improve quickly without being frustrated! Highly recommend to anyone learning to play golf. ### 5/5 — Takes the guess work out of putting *2022-04-17* A lot of other green reading systems out there are only good for a certain type of grass. SLOPEGRAIDE is amazing whether you’re on Bermuda, bent grass, etc. I’ve noticed a drastic improvement judging speed and brining it together with the desired line I feel comfortable playing. A must have if you want to take your putting to the next level. ### 1/5 — Ripoff *2022-03-31* They don’t tell you it requires you to buy $140 device for the app to work! **Developer response:** We are clear in the app description that a Slopegraide sensor is required to unlock full functionality of this app. The newest feature of our app Slopegraide AR, does NOT require a Slopegraide sensor, however a paid in-app subscription and compatible iPhone or iPad Pro is required. The requirements of our app are also listed on our website as well. ### 5/5 — Never Forget This App When Practicing Your Putting! *2021-12-09* This app has changed the way I look at green reading and making putts as a competitive golfer! Especially with the latest update in 2021 with speed, slope, & directional information all at once I can confidently know I’m reading and pacing my putts properly to get the most feedback out of my practice sessions! The new “ballmarker” mode changed the versatility big time for this product! ### 5/5 — Needs an external device *2021-06-07* Doesn’t use phone accelerometers **Developer response:** We have made it clear in the app description that a Slopegraide sensor is required to use this app. To purchase a sensor, please visit our website at www.slopegraide.com. ## Frequently asked questions about Slopegraide ### What is Slopegraide?
