Car Log is a small app to log and keep track of the fuel consumption of the personal "car fleet".
It allows the tracking of multiple cars and is able to provide statistics about the mileage, average fuel-consumption and total fuel-consumption.
Depending on the user's selection, the app will present this data in numerical form or through pie-, bar- and line-charts.
This app does not require any special permissions to run. Should this change in future versions, a detailed explanation about why and how will be provided here.
Please see http://www.dimensionv.de/CarLog for more information.
There is also a user-manual (with more screenshots) availabe here: http://www.dimensionv.de/CarLog/manual
If you like to try the app first, there's also a free (ad-supported) version of this app available on Google Play, called "CarLog Free". As of now, it has the same functionality as the paid version.
