Yes, you may now track both vehicles on both phones.
The easiest way to combine the data will be to create a single Fuelly account. Then both login to that account.
The data from your phone will sync to Fuelly. When your wife logs in, her vehicle will sync to Fuelly and your car will sync from Fuelly to her phone. You'll sync her vehicle from Fuelly the next time you open the app.
If you are both independently tracking the same vehicle, that is much more complicated. It would be best for you to contact
support@fuelly.com, be sure to include your backup data.
