You might want to check out a project I am working on if you like to go out to bars to watch UFC fights
. It's not a native iPhone app (yet), but if you go to the URL in Mobile Safari, it should work well for you. Android users shouldn't have any issues either.
I should also say it only works for U.S. locations right now, but Canada is coming soon and UK in the future.
Would love to hear what you think. It's a labor of love for me and so far the response I've gotten on it has been mostly positive. Check it out.
