The app would be 5 stars except it seems to only focus on the eyealign putter, theres no content about the 2016 adjustable putter with its loft, lie, offset etc.
Love it. Tells you exactly how to adjust your putter from this company. It's awesome. ....
We have been working hard to update the Happy Putter App! In v2.0, we made changes and updated the content to reflect our newest putters in the Eye Align Series. This updated includes:
• Visual Diagnostic Test
• Access to the three alignment guides that come with each Eye Align Series Putter
• USGA Rules added regarding adjustability
• Updated information on how to adjust the Eye Align Series putters
GSA PUTT captures putter motion and analyzes your putt in amazing detail.
