I can recommend organic maps: https://organicmaps.app

The quality of the maps depends on the region, though. But for me it is typically good enough. I not only like the local maps, but also that I can save waypoints locally. And I can contribute things like points of interest to Open Street Map directly via the app. In my opinion, the biggest disadvantage is that there is no traffic information.

Another vote for Organic Maps. I use it as a lightweight maps app for backcountry or traveling in foreign countries where I don’t have a sim card. You can also record tracks in the app, or import .gpx files. In airplane mode it has low impact on battery consumption.

I was also pleasantly surprised to find out iOS Star Chart app (https://apps.apple.com/us/app/star-chart/id345542655) functions entirely offline. Recently used it while camping, and it just needed a GPS coordinates fix to adjust sky map to location.

Might be better to switch to the CoMaps fork:

		Interestingly, f-droid doesn't initially show CoMaps but does show Organic Maps because apparently CoMaps doesn't pass an antifeature filter for depending on a tethered service on codeberg. I don't quite understand why this is an issue; they both need to download their maps from somewhere, don't they?

		Thanks for recommending. I was not aware that a fork of Organic Maps had been created, or that longtime contributors to OM had concerns about the project.
