A Windows Phone app for tracking mileage and maintenance on your vehicles
At this time it offers mileage tracking, though the data file has room for the maintenance. I just haven't added those pages yet.
Currently the app will compile for (and targets) WP8.1 It has been submitted and accepted in the WP store, so you don't have to compile yourself. If you would like to download it, it is live in the store here: https://www.microsoft.com/en-us/store/apps/open-road/9nblggh1rgz5
