Putt Buddy unleashes the power of your LiDAR-equipped iPhone to automatically measure the distance, speed, and outcome of your practice putts with astonishing accuracy! With Putt Buddy's simple and intuitive interface, setup is easy and takes under a minute. After a quick walk around the putting area to show Putt Buddy around, just set your iPhone in a stable location, enter the frame, and...start putting! Your location is tracked in real time and in three dimensions, allowing you to putt freely from pretty much anywhere within frame. Each session has its own statistics and photo(s), which you can overlay with your putts' trajectories to visualize trends and identify problem areas. Cumulative statistics and graphs are also provided to track your progress over time! Putt Buddy also includes Quick Measure, a tool that combines the accuracy of a tape measure with the speed of walking it off! Have you ever been on the putting green and wondered whether or not you're inside Circle 1? Or maybe you sunk a huge putt and wished you could know EXACTLY how long it was to properly gloat to your friends? Silly questions, of course you have! With Quick Measure, you'll never have to wonder again. So get out there and brag about that 43.6 foot putt you sank in your solo practice round! Putt Buddy is free for a week and if you like it, it costs the same as a new Tour Series disc from your favorite pro for AN ENTIRE YEAR! And it's way more likely to improve your game, I promise. Plus, your support helps me continue to build and improve on Putt Buddy, because this is only the beginning. Happy putting, and don't forget to enunciate!
