By registering fuel data you are able to track the fuel consumption both in graphs and as a summary. All costs related to a car can be added as events which then add on to the total summary of the car. Under Settings you can select the units to use.
There is also a built in journal function where you register predefined distances. Those can then be compared with the total driving distance to show the ratio between private and business driving. All the data can be exported to your One Drive account.
