Tiger Woods 12 for iOS Free
TheSandTrap.com Top Picks
It's probably free because it's so buggy. Constantly crashes, locks up, announcer audio will repeat itself on a loop, etc.
I don't think I was able to play more than 6-7 holes without a crash when I first bought it. Once iOS 6 rolled out, it seemed to iron out a lot of issues with the game (and a few other apps). Then EA released an update post iOS 6... which made gameplay even worse. I can't go more than 3 holes without a total crash now.
