The Slopegraide Story

"I remember how frustrated I was one day after missing every single birdie putt I looked at on the low side of the hole.  


I was hitting the ball really well, but I lacked confidence and trust with my ability to read greens.  


I went to the practice green immediately after my round to work on my green reading, but I felt silly moving a digital level around from spot to spot.


I kept thinking as I kept bending over to move the level that had to be a way to make this process quicker and easier.  In that moment, the idea of Slopegraide hit me."

Founder / Creator of Slopegraide

Professional Golfer

Anyone who has played golf knows the frustration of misreading putts all day on the green.  Distance rangefinders and other GPS technologies help get you from tee to green, but once you're on the green, you're on your own.


We recognized there was a missing piece in golf technology that needed to be addressed.


In understanding the challenges of green reading, we've combined mechanical and software engineering talents to create an easy-to-use tool that will accelerate your growth and development in green reading. 

With you, the golfer in mind, we created Slopegraide, golf's first wearable green reading system.


Slopegraide takes your stance and displays a reference point in real-time on your iPhone or Apple Watch that tells you where to aim any putt you have inside 30 feet, like a distance rangefinder.  


This information will help you eliminate the self-doubt and guesswork with how your putt will break, so you can make a natural putting stroke and hole more putts, lower your scores, and take your game to the next level!
