I am an avid golfer and investor in ONCI, but I can guarantee you that their app will not take 2 hrs off a round of golf. Not even a chance. The game of golf requires a lot more thought than what club to hit. Height of the shot matters, cut of the grass, thickness of sand in bunkers, speed of the greens, etc... might be cool as far as a distance tracker and something to keep historical scores, but to think it will cut two hrs off a round is nonsense.
