What is Slopegraide?

Slopegraide is a smart ball marker that connects to your iPhone, iPad, or Apple Watch and reads the green for you in real-time!

What separates Slopegraide from other products on the market is the abundance of valuable data the app provides. Slopegraide shows you not only the slope value and direction, but also where to aim your putts and HOW to putt them!

"Slopegraide is helping me build my knowledge of green reading in a way that I never could without tour-level instruction. It’s clearly paying dividends already. Slopegraide is dramatically improving my putting ability at a competitive level that would otherwise take years to achieve."

"This product is amazing. So simple to use and it really improves your putting. I shot 5-under yesterday including making a 40 footer. The low scores were from sinking critical birdie putts. It's great to see how I can learn how to read putts better from seeing what I am missing."

Colby D.

"So far I am really liking everything. I can tell already that strokes are going to fall off my scorecard. I am now dropping more 20 footers that I normally wouldn't make. All I can say is wow!"

"I was reluctant at first, but it helps train my body what it feels like on different slopes. It works and it's pretty dang accurate. Before every round, I practice putting to get my mind and feet on the same track with this device. Then I go play. It's been spot on."

Louis N.
Scratch Golfer

"This device is legit. I can't wait to use it more on the course! Everything 15 feet and in was money. And even the longer putts were tracking the whole way!"
