The app does not currently support mileage tracking; however, there is a roundabout way to keep track of the number of miles driven during a single session. The effort requires entering mileage data in the notes section. By entering the number of miles traveled in the notes section, you can export the driving log data to a .csv file and utilize the functionality of worksheet software (Excel, Numbers, Google Sheets, etc.) to calculate the number or miles driven.
The app is designed to for a single user; however, there is a workaround that makes it possible to use the app with multiple users. The notes section can be utilized to track multiple drivers. In doing so, you will need to export the data using the backup feature and sort the resulting .csv file by the notes column. The functionality of the worksheet program (Microsoft Excel, Google Sheets, Numbers, etc.) will allow users to total the time and track the skills.
