주유도우미 is an Android app developed by Hana App that provides users with the fastest fuel price information based on their current location. Users can easily find the nearest gas stations and compare prices within a 3km, 5km, or 10km radius. The app allows users to filter results by fuel type (premium gasoline, regular gasoline, diesel, or LPG) and even save their preferred gas stations for future reference.

In addition to providing accurate and up-to-date fuel prices, 주유도우미 offers convenient features such as integration with popular navigation apps like T-Map and Naver Map, as well as the ability to share information on Twitter. Users can also manually set their location if GPS accuracy is compromised.

Please note that while the app strives to provide the most accurate information, there may be a delay of 3-4 hours in reflecting price changes at specific gas stations. This is a common issue across all fuel price information platforms and websites.

Overall, 주유도우미 is a reliable and user-friendly app for those who want to find the fastest and most affordable fuel options in their area.
