If you’re married and filing jointly, you can share your Hurdlr account with your spouse to track both of your mileage. To do so, just make sure you’re both logged into the same account on your respective devices. Hurdlr will track the trips detected by each of your phones. 

Note: If you are driving in the same car at the same time and both have automatic tracking enabled, it will track the trip on both devices. To avoid duplicating the trip, you can either delete it or one of you can turn off the automatic tracker before driving, so the trip isn’t tracked twice.
