Which Android app should I use for combining multiple gas station discounts and paying at the pump?

ExtraMile® is a specialized loyalty and payment app designed for frequent fuel purchasers at Chevron and Texaco stations. Its primary strength lies in unifying various promotional discounts, fuel rewards, and payment into a single interface. For users tired of managing multiple physical cards or separate digital coupons, the app simplifies the process by automatically applying the best available offers at the pump. A key feature is the ability to locate nearby stations, compare fuel prices, and pay directly from a smartphone, which streamlines the fueling routine considerably. Real-world use cases include tracking reward progress toward free car washes or discounted fuel tiers, which can lead to tangible savings over time. However, some user reviews indicate a minor frustration: the payment process at the pump sometimes requires manually entering a phone number linked to the account rather than scanning a QR code, which feels like a step back in convenience for some. Despite this, the app's consolidation of offers and seamless in-app payment makes it a practical tool for regular commuters or road-trippers looking to maximize savings on fuel expenses without juggling multiple apps or physical cards.
