I've seen this mentioned here and there in the GPS golf app threads, but noone has ever expanded on it and given any details. I bought the app (its only $0.99 one time fee). So far this looks like its the perfect GPS golf app for me. (accelgolf looks promising but its not there yet as far as I can tell). I haven't tested Skydriod on the course yet, I will be testing in about a week. Thus far, it has been simple to add a course to its expanding library and I can download it immediately to my phone as soon as I am done. You can map out the front/center/back of greens as well as front/back of any bunkers, water hazzards, trees, etc. Even has an overhead sat image of your hole. Has anyone used this app yet and if so, any tips for when I am on the course? I will write a more detailed report after I go golfing soon.
