It could be but if I open and search on GMaps, I’ll likely just end up using GMaps.

I think this other app used different source data for addresses (eg Google Maps or Mapbox API) because OSM business and address data is often very out of date and incomplete

Yes I’m aware you can search for addresses in OsmAnd, but the reality that I’ve experienced is that the address data in OSM in general is wildly unreliable (aka OSM and CoMaps often don’t have the business name in the app, and many times even searching the address yields no results).

I believe that this app used a different geocoding service where address data was more reliable to do geocoding, and then when you picked the address you were searching for it would auto-open OSM and pass the geodata into the search field. It legitimately enabled me to use OSM / Organic Maps. Now without the app I’m back to being forced to use GMaps much of the time because places I’m navigating to are literally not findable via the search bar.
