I did research about what types of gas are sold in gas stations and interviewed some of my friends who drive gasoline cars. Here is the question I want to solve in UX design: 1. See all nearby gas station prices in a straightforward way. 2. It is easy to select a specific gas station to know detailed information and can save them as a frequently used gas station. For UI I want to make it user friendly especially when people are driving. So, I: 1. Less the information content to be simpler and clearer. 2. Color contrast is user friendly.
