I used to use a calendar and Google maps to create a spreadsheet as a mileage log. It worked well for several years, but this year I’m using an app on my iPhone.
There are several including
Track My Drive
Some offer features such as GPS tracking. Several apps are free, but most cost from $.99 to $4.99.
