ok, well I finally made it out to the course so I thought I'd clear up any confusion on this app.
accelgolf is just starting out, it has some promise but for me, it just isn't there yet. It looks like a cool shot tracking tool where you can see some stats on GIR, sand saves, 3 putts, etc.
The range finder portion is what is lacking. Currently, you can see an overview of the hole (think it uses google maps) and thats great but it doesn't automatically tell you your distance to the green. To do that, you have drag a point on the screen to where you are at and getting that precise is nearly impossible.
If they ever make it automatically take your position and show you how far it is to the green, then they will be well on their way to a great app. For now, free apps like freecaddie work just as well (minus the overhead view and the shot tracking ability).
For me, I just want to know how far it is to clear that bunker on the left, or what the front/center/back of the green is. I will keep an eye on accelgolf for improvements but it is now off of my phone. I went and bought skydroid for $0.99 which does everything I need (distances to front/center/back of green, front and back of hazzards, and a satellite overview of the hole)
