Current Version 2.0.46 (26th Sept 2020)
Download From Google Play Store
MPG Calculator is split into three tabs, Edit Record, View Data, and View Summary.
Simply enter the Litres, Fuel Price and Vehicle Mileage on the first tab each time you buy fuel. The date will default to today's date, but you can change it if you're entering details for a fill-up you made previously. Each fill-up will appear in the "Data" tab in the form of a table. If you made a mistake, you can delete or edit previous records by long-pressing on them in the "Data" tab. View the "Summary" and "Charts" tabs for summary information on all the data entered for the selected vehicle, such as date ranges, mileage ranges and fuel economy.
Since version 1.3.0, multiple vehicles are supported. Select "Vehicle List" from the main menu to change vehicle. A completely separate set of data is stored and summarised for each vehicle. Vehicles can be renamed by long-pressing on the vehicle in the "Vehicle List". The data export and import also now supports multiple vehicles, including vehicle names. (See Data Export below). Importing a previous version export file will simply assign all the data to the first default vehicle. The currently selected vehicle is displayed at the bottom of the first screen.
Since version 1.4.2, fuel records have a "Premium Fuel" flag. These are indicated in the data list by an asterisk next to the litres. The total MPG per vehicle is calculated separately for normal and premium fuel types, so you can compare how well your vehicle responds to premium fuel, and whether it's worth the extra cost.
Note: The MPG calculations in the data list will only be correct if you fill the tank completely each time.
UPDATE: since version 1.2.1, the export process displays a message specifying where the export is saved. I've had quite a few queries about this since more modern phones (newer versions of android) with built-in storage might place the file in different places.
The data can be exported to the SD card for use in a spreadsheet or as a backup or if you are changing phones. Data can be imported back in later, and will overwrite the current database, so be careful! The file format is a standard CSV file and the columns are as follows:
MPG RECORDS | |

Two record types are included from version 1.3.0 onwards. The first column specifies the record type. M for a mpg record, and V for a vehicle record. | |
