[Talk-us] Smartphone App that searches OSM addresses?

[Mike N]

In the case where a county completely revamps its road network and 
addressing scheme for E911 purposes, then authorizes its road and 
address data to OSM, and it's properly imported, are there any 
Smartphone apps for both Android and IOS that would search those 
addresses?   And have turn by turn routing.

   My cursory review:

   OffMaps2 - Yes on address search, no on routing
    GPS Nav - uses commercial address reference over OSM address
    Scout - "  "
     OSMAnd - theoretically Yes on Android (I haven't tried it), I can't 
get any OSM address search to work on iPhone

  Any suggestions?
