MPG Tracker is an Android app developed by WildStudios that allows you to easily track the MPG (miles per gallon) of multiple cars. With this app, you can input information about each car you want to track and record details about each time you fill up the vehicle with gas.

While the app may not have the most visually appealing design, it provides a straightforward and efficient way to monitor your car's fuel efficiency. You can update the information you entered previously, ensuring that your mileage data is always up to date.

However, it's worth noting that there is a minor issue with the MPG calculation for the first entry. The calculations for subsequent entries work correctly, and the developer has acknowledged this bug and promised to address it in an upcoming update. Additionally, the next update will bring improvements to the app's navigation and allow for incomplete entries and cars without a nickname.

Overall, MPG Tracker is a useful tool for those who want to keep track of their car's MPG and monitor their fuel consumption. With its upcoming updates, it is expected to become even more user-friendly and reliable.
