Best app for finding gas stations while traveling?

I use Waze for driving directions anyway, so i just use their gas finder most of the time. Last year when half of the country was out of gas, I used gas buddy to find stations that had gas currently. It was more up to date with that sort of info than Waze/Google.

I haven't had much chance to use it yet, but my MIL swears by the iExit app
