Acastus is a completely private, free and open source Address / POI lookup
application for Android. You can use it to find nearby places, all without the
privacy invasions and tracking features of other apps – or share your location
to other people, knowing full well that the information is kept private.
Acastus relies on
Pelias as the backend,
a replacement for Google Maps and other geocoding services that you can run on
your own server. It uses the pelias-api to fetch results to your phone, allowing
you to search for places in Acastus. Then open and navigate to the result in
your preffered navigation app, such as OsmAnd or Maps.me.
