If you own a personal, valid zone subscription you have the possibility to save the zones, for which the subscription is applicable, in the app.
Open the menu item "Ticket Settings" and enable the item "Do you own a zones pass?". Then you only need to choose the tariff community, the zones for which you have a zone subscription and the expiry date of the subscription.
If you check in at a station within a zone with subscription and then travel outside this zone the saved zones aren’t charged. If you start your travel outside the saved zone the saved zone is also not charged. In both cases the travel distance outside the saved zone is charged with a conjunction ticket.
The 9 O'Clock subscription (9-Uhr-Abo; available the tariff community Passepartout) cannot be added to the app.
In case of ticket controls the valid subscription has to be presented to the control staff without explicit request together with the smartphone for control purposes
