Hi @TadasC
Sorry for the delay in responding to your questions:
> Europe map into app for routing, geocoding and turn-by-turn navigation.
I recommend looking into ArcGIS StreetMap Premium (https://developers.arcgis.com/qt/route-and-directions/add-streetmap-premium-data/), it supports geocoding, routing, and turn-by-turn navigation.
> Is it enough to use ArcGIS for Developers with Builder subscription to achieve this task, or we need other subscription?
If your app is revenue-generating, then an ArcGIS Developer subscription plan at the Builder level (or higher) will be required.
> How mobile app installations will be accounted from ArcGIS side? Do we need to buy license for every mobile app installation?
Yes, you need to keep account of mobile app installations and ensure each one is licensed. For more info see: https://developers.arcgis.com/faq/#licensing-runtime-per-deployment and https://developers.arcgis.com/faq/#licensing-runtime-license-string-distributed.
The good news is that for the license, you might only need a Lite (free) license, and the StreetMap Premium license.
Alternatively if you are selling your app to organizations with existing Esri software, you may find users can get an ArcGIS Runtime license by authenticating with an ArcGIS Identity. For more info see: https://developers.arcgis.com/faq/#licensing-runtime-named-user-license-levels. The ArcGIS Identify would need to be the equivalent of a Lite (Viewer or higher) but they would also need the Streetmap Premium extension/entitlement.
Thanks
