A) Why would you need to look up the size of your tank? The gas pump tells you quite precisely how much you used since last fill-up B) Nobody said they needed

A) Why would you need to look up the size of your tank? The gas pump tells you quite precisely how much you used since last fill-up B) Nobody said they needed an app for this C) I'm not really sure how pulling up the calculator app and punching in numbers is any easier than pulling up the mileage app and punching in numbers D) If you use your imagination very slightly, you can come up with other obvious features such an app would provide, such as tracking average miles driven per day/month/year, average MPG per day/month/year, gas prices over time, service records (when was the last oil change/tire rotation/brake job), etc. E) I also explicitly talked about another feature it provides (reminders), so I don't get the impression you actually read my comment before replying
