GasBuddy helps users find the cheapest gas, find gas stations by price or location, alert users when prices go up and also inform the future users about past experiences with gas station services. GasBuddy is a locale based app which utilizes the “location/map functionality (GPS)” on a user’s smartphone and information it receives from gas station operators and users to find the lowest gas price in any particular location. Strengths: ? GasBuddy possesses an elegant and user-friendly interface which is easy to understand and navigate even for a new user. ?
