Context

A client commissioned a mobile app that, given the user’s location and a configurable radius, shows the cheapest gas station and orders the rest by price. They also let us publish it for free on the official stores, a collaboration where the case serves as a technical showcase for us and a useful service for the end customer.

Solution

  • Native iOS (Swift) and Android (Kotlin) apps.
  • Integration with the official fuel price dataset, real-time updates.
  • Interactive map with an orange-highlighted marker on the cheapest station within the radius.
  • Continuous geolocation with correct permissions and battery-saving mode.
  • Alternative sorting: by distance, price, brand.
  • Published on AppStore and Google Play as GasOn.

Result

  • Functional app in production on both stores.
  • Client gets visibility; we demonstrate mobile-first capability with live data.
  • Useful reference for projects involving geolocation, real-time data and polished native mobile UX.
