Since the odometer setting in the app and the car get out of sync, maybe once a week, ask me to manually update my odometer. This is what the DriversNote app does, and it's very easy to do and keeps the odometer relatively close from week to week. (I currently subscribe (paid) to their app, but am test-driving TripLog ATM, and am seriously contemplating switching when our subscription with them expires in May.) Thanks for reading
