What's a good iOS app for snagging deals on gas and smokes when I'm already running late for the job site?

Look, I'm not gonna lie, the Circle K app ain't winning any design awards. The tutorial is useless, but once you figure it out, it actually gets the job done. I use it mostly for the fuel discounts 'cause, let's face it, the truck guzzles gas like it's going out of style. Plus, they got deals on coffee and snacks. It's not life-changing, but when you're trying to save a buck or two on the road, it's actually rugged enough. It ain't fancy, but it's like a dependable hammer – gets the job done, even if it's a little rough around the edges. Battery life seems okay, haven't noticed it draining my phone too bad yet, which is a plus. And hey, sometimes they got freebies, can't complain about that.
