This app is a very simple one. It will display an aerial view of the golf course you are on and it allows you to pick points on that view and find the distance. So how does the average golfer use this app?
Well, when you walk up to the tee and want to know how far away a tree is from where you are hitting, you can look for it on the aerial view, click the tree and find out how far it is away. This is very helpful for those tight holes where you can overdrive and end up in the trees, the water hazards, or the sand hazards. It does this feature much better than my handheld Bushnell Golf Range Finder which works by pointing your sighting at the tree and reading the distance.
It also aid by providing an aerial view where you can identify whether or not their are water hazards or other challenges over a hill, hidden by a tree or dogleg. Since the view is from a satellite, it gives an up to date view of course conditions-- in Florida, sometime lakes appear after rainfall then dry out.
You can also find the distance very accurately on your approach shot and to determine exact distances for a carry over water.
For what it does, and for it's price, this app is better than none at all; but there are much better choices for the price, features available.
