I went on the course this morning with this App GolfSites. First I need to add my club set to this App. This is not apparent until the point you enter your score.
I had downloaded my course (Brookside) the night before so I can try run this App first. Brookside is in a valley and don't have good signal for my iPhone so I want to make sure I have the course.
Turns out even when there's no signal, the GPS runs just fine, maps all there. Potentially great because if I go on vacation, I don't have to worry about roaming data charges on my phone bill.
This App uses a strange way to enter score, it's like the shape of the course. So when I hit a ball, I press Tee button, then it will ask me which club I use, I picked the driver. Then my second shot in hole 1 is on the left rough, I press the left rough button and then it ask me which club i use. So everytime I hit a ball, I press 2 buttons. It's quite easy as you get the hang of it. First few times a bit distracting and forgotten to press buttons. But after a while it's simple. The press of buttons marks my location apparently.
At first I am used to the scroll wheel like GolfShot to enter score. But I don't like this type of entering because I have to think too much and that takes my mind off my game. GolfSites way is a "no brainer" for a non tech person like me.
After the round, I saved my round and when I go to review it. Wow! I see my ball path outlined in green and blue. Maybe not all is accurate, as they did not show shots in some cases, I suppose it's too small to be viewed on the iPhone. But overall, it's a great way to review the game.
The rest of the features are pretty much like all other features I have seen on the App store.
Believe me, I checked a lot of them.
By the way, I charged my iPhone 4 before I go on the course and end up using 50% of the battery. I do use the sleep button quite a bit too.
