The Petrol App, developed by Solid GEAR in collaboration with CARTO, is an iOS application that helps users save money on gas prices. The app uses geodata to calculate a user's distance from fuel stations and gasoline prices, providing recommendations for the most cost-effective route. With its Mobile SDK, the app enables users to filter data by brand, rank nearby stations based on price and travel cost, and compare gas prices region-by-region across Spain. The app also incorporates daily data sync with Spain's Ministry of Energy for up-to-date gasoline prices, allowing users to make informed decisions about their fueling stops.
