Apple and Google do not allow sharing of subscriptions across devices however there is a workaround for this.
Please go to www.tripwizard.rvlife.com and login using the same login credentials that are used to login to the app. RV LIFE Trip Wizard is included with your RV LIFE Pro subscription.
After you logon to RV LIFE Trip Wizard, this will attach the subscription to your email address. On your other devices, open the RV LIFE app, go to the Profile & Account page, sign out and sign in again. At this point, the subscription can be shared.
