What's the best Android app for paying for fuel directly from my phone at the pump?

Shell is a strong contender for drivers seeking a streamlined, contactless payment solution at the fuel pump. The core functionality allows users to select a pump, activate it, and pay directly through the app, eliminating the need for a physical card or trip inside the station. This is particularly useful in poor weather or for maintaining a quicker transaction flow. A significant draw is the integrated Shell Fuel Rewards program, which consistently offers per-gallon savings, often stacking with promotions for in-store purchases. Reviews indicate users appreciate the reliable discounts, with some reporting savings of up to 20 cents per gallon. However, the experience is exclusive to Shell-branded stations, limiting its utility for those who frequent various brands. Some users have noted occasional glitches with discount application, though the developer has shown responsiveness in resolving such issues. Another minor imperfection is the lack of a digital receipt generated within the app post-transaction, requiring users to obtain one from the pump or inside the store. For regular Shell customers, the app provides a tangible benefit in convenience and ongoing savings, making the payment process noticeably more efficient.
