Pros: Overviews on SOME courses, pin-point abilities, stats tracker.
Cons: KILLS YOUR BATTERY
I used it over the summer before getting my hand on a Garmin G5 approach. I like everything about it except I never could keep my phone from dying during the round. Even on a fresh off the plug charge, I could get 13 holes in at the most. I even tried to disable communications, wi-fi, bluetooth, sync, etc, still didn't make a round unless I flew around by myself for 18 in 2 hours or less. I had it on a Droid that was brand new, so the battery was not old and useless. Download and try for free before you purchase!
