What's the best iOS app for finding cheap gas on a road trip?

Gas Prices is a straightforward utility designed for drivers looking to minimize fuel expenses, particularly during longer journeys. The app aggregates user-submitted and station-reported pricing data to display cost per gallon at nearby stations, which can be filtered by fuel grade and station brand. A key feature for road trippers is the ability to search along a route, allowing for proactive planning of fuel stops instead of making costly last-minute decisions. The map interface is clean, showing prices clearly with color-coding, and directions can be launched directly into Apple Maps or Google Maps. However, the accuracy of prices depends heavily on user contributions in a given area, so data in less-traveled regions can sometimes be outdated. Reviews indicate the free version is sufficient for most, though an ad-free experience requires a nominal one-time payment. While it doesn't offer advanced features like trip cost calculators, its singular focus on price and location makes it a reliable, no-fuss companion for budget-conscious travel.
