Free version used. Does what it says it will. Used on Nexus 6P and it showed that my battery had degenerated over the last few months. Now have a new Pixel 2 XL, so will no longer be needing to use it. Good diagnostic tool. Not bad
Was playing the game regularly, getting better as like in real golf it isn't easy, gotta keep playing to get better. Recent constant daily 300-400mb updates wiped me out, cost me heaps if money on data from my network provider which I can't recoup. By the time I'd had enough of this and un installed it I found it's total game size was over 3GB fun though Flawless
Problem fixed. Had a small issue with the app and was able to fix it thanks to the devs replying to my review (not really, I just poked around a bit more and fixed it myself, but give them credit for being attentive ^.^). Very useful app. Highly recommended. Perfect!
