Computer Rock has realized a complete rebuild of the ready to app on basis of a professional and thought-out app architecture. It is now possible that the app can be extended by new services, three new services have already been integrated with the first release of the rebuild. The setup offers the possibility to implement new services natively in the app as well as services that have been developed via a 3rd party. Thus, the highest possible flexibility of the app is guaranteed, so that future programming costs can be significantly reduced.
