Add a small graph with the history of prices for the current pump to see periodicity of it

I am not able to track gps on a trip over multiple days. I start and end my trip manually because the trip is over multiple days so the automatic start/finish won't work. What do I need to do to get the gps map recorded and viewed as a route on a map? 

I added a fuel up twice by mistake. How do I delete the last one?

How does Setup Tank Level works in Mileage log if it's checked?

Please explain.

Sorry for being so stupid but I didn't get how reminders works. I set up reminder for a certain day. The day has come a nothing happened :-( No push notification, nothing when I started the app. So what is the reminder for?

I also didn't find a way to show list of reminders. There is no option in the menu :-(

Can anybody give me a tutorial how should reminders works and how to be notified when it reaches the day / odometer state ?

I started using auto-launch and for most trips it works perfectly OK - trip starts when phone Bluetooth connects to car and it ends when Bluetooth is disconnected. However, despite "start" works reliably, the "end" does not - on some occasions the trip continues to be "in progress" and it only finishes with the end of the next trip. There is even no way to finish the trip manually (it does not show in notification center).

I have a car I am modifying and want to see if my gas mileage improves.  Is there anyway to reset the MPG stats for this vehicle and leave my other intact?

There is no way to stop trip log.
