Driving diary vs. mileage log
Both keep a list of your drives, but they answer different questions. A mileage log proves the business use of a car to someone else. A driving diary is for you. Yesterdrive is a diary.
What a mileage log is for
A mileage log is a formal record kept for an employer or the tax office. The rules depend on the country, and they typically ask for things like odometer readings and the purpose of every trip, in a form that can be checked later.
What Yesterdrive is
Yesterdrive records every car trip on its own and turns your history into maps and statistics worth looking back at: the route colored by speed, the roads you had never driven, your weeks, months and years. There is no account and no server of ours. Your trips stay on your iPhone.
Why it is not a compliant mileage log
Distance comes from GPS, not from the odometer, and the app does not store odometer readings. A missing trip can be added by hand with an estimated route. Nothing in the app certifies a record for an employer or a tax authority, and it was not built to any country's rules.
What you can still do with your trips
You can give each trip a category (Business, Personal or Commute) and a note. With Premium, new trips that start during your work hours can be marked as Business for you, and the summary export writes one row per trip to a CSV file: start and end, from and to, vehicle and license plate, distance, driving time, category and note.
That file is plain data. It can help you with your own records, but it is not a compliant mileage log.
Which one you need
If you have to document business trips for reimbursement or tax, use a tool built for the rules that apply to you. If you want your drives remembered without doing anything, that is what Yesterdrive is for.
Let the next drive record itself.
