You can download QuoVadis Mobile for iOS from your App-Store.
After starting QuoVadis Mobile via QVM-I-Icon on the home screen, the start page appears from which all functions are available:
Map, GPS, Find, Database, Live and Help (this Wiki)
As usual among iOS, QVM-I is closed by opening the App overview via a double click on the home button and then wiping QVM-I upward.
Via in the upper right corner you see at Info the used version number of the App and you can access the global Settings.
