Preferably Android apps available through F-Droid, but feel free to recommend iOS apps, too!

On iOS, I really like Sky Guide—I don’t think it’s open source, but it has the right features for the casual star gazer like myself, specifically the ability to point my phone at an object (i.e., “what’s that object up there”) and/or search by name (“where’s Jupiter right now”). After my transition to Android, I’ve found Sky Map, which has good feature parity with Sky Guide.

Any other open source apps like Sky Map that I haven’t found yet?

      No biggie, but reading the ToS in the app, it states that the app will send anonymous usage data to Google. I’ve disabled its network access (possible on GrapheneOS), and it works anyway. On this topic, the description in F-Droid reads:

      Do I need an internet connection? No, but some functions (like entering your location manually) won’t work without one. You’ll have to use the GPS or enter a latitude and longitude instead.

        FWIW, it says you can opt out of this in the settings. It’s sort of crappy you have to go digging to find this. There should be a disclaimer. Thanks for pointing it out.

          I’m running it without any Google services (on this user profile), not even sandboxed. Would it not work for you when attempting, or have you just seen or heard somewhere that it wouldn’t?

      Stellarium is an amazing planetarium program, almost unbelivable it’s open source.

      But it’s android port is a bit disappointing, to be honest.

      I’ve seen this app recommended in other articles; unfortunately, it is unavailable on F-Droid, so I’ve yet to try it for myself, but thanks for the recommendation.

          Where would I find the Android releases of Stellarium to do so? Their github only hosts Linux, Windows and MacOS releases.

          Looks to me like Stellarium mobile is closed source because they want to monetarize Stellarium mobile +.

      I had found this app as well, but couldn’t get it to point & shoot so to speak. Seems I must manually tap and drag to pan around the map. Am I just doing it wrong?

        Yes, that’s my understanding. So it’s more work to use than point and shoot, which would be a nice feature for someone like me who can recognize major constellations and planets, but not much else.

    i go to https://www.timeanddate.com/astronomy/night/ which is not really an app and it can be a bit wonky at times but it works better than every mobile app i’ve seen.

    the desktop version of stellarium is the only worthwhile open source program i know about.
