I love it. I have Arccos, I find it pretty unobtrusive, and during the round I like overheads of the holes, especially for courses I'm not familiar with, along with the F/M/B yardages on approaches. The recommended club is a little iffy because it doesn't take into account elevation, but otherwise, I think it's pretty solid. After the round I can see where I'm struggling the most so I can focus a bit more on those areas when/if I can practice. It's one thing to feel like your iron play wasn't so hot but was made up for by that one great iron shot, it's another when it says your GIR was bad. You can say "I had a couple good birdie putts last round" but that app will let you know how many putts you actually had.
