Which iOS app is best for saving money on gas at convenience stores?

Circle K is the official companion app for the convenience store chain, designed specifically to help customers save on fuel and in-store purchases. The app’s primary utility centers on its fuel savings program, which allows users to activate discounts directly on their phone before pumping gas. Reviews indicate users appreciate the tangible savings, with one noting their premium fuel price was reduced to match regular gas costs. A key feature is the integration of the 'Sip & Save' beverage program and other rewards, which can be managed digitally to earn points towards future discounts. For real-world use, the app simplifies the payment process at participating locations, letting users skip the card terminal. However, the experience can vary by location, as some user feedback points to inconsistencies in staff helpfulness. The app also pushes promotional deals on snacks and drinks, positioning it as a tool for overall trip savings, not just fuel. While generally reliable, occasional syncing issues with the station’s pump systems have been reported. For anyone regularly visiting Circle K locations, the app provides a straightforward method to capture available discounts.
