Review on Digital Mileage Logbook - Little LogBook: No Monthly or Annual Charges by Jason Lockwood

Does what it's supposed to. This is just an odometer, you cannot track the vehicle in real time or set up geofences etc. so there is no monthly fee. I use this to track my personal vehicle which I use frequently for business. I can easily track individual customers and bill them correctly. And if the customer has a dispute, I can show the log. It seems well made and the software is simple and easy to use.
