CoMaps: https://www.comaps.app/
It's a fork of Organic Maps, after some drama. Only minor changes so far, but it's what I've started using as my main maps/navigation app.
Some info on the history including the timeline leading to the CoMaps fork is listed on the about page.
But basically this is a maps app, where you can:
- View maps based on Open Street Map. Maps are downloaded to your device, so you download your region then you can navigate offline.
- Navigate by car, bike, walking, and in some areas (not mine π), public transport.
- Search for places, see opening hours, website, phone number, etc for places where the detail is on on OSM, and you can add the details yourself if they aren't.
- Save places for easy navigation
