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.

          It’s off by default, it seems, in version 1.10.4 RC1 from F-Droid. At least, I went to toggle it off, but it was already done.

          Note, I tried rejecting the ToS st the first run, which just closed the app. So… I accepted them at the second run… Though, I don’t know if that in any way really could have affected the setting.

        “entering location manually” worked without GPS for me.

        netGuard blocks all new apps by default for me and i get a notification if they try to access the internet. Sky Map doesn’t have any listed attempts (no gms on my <s>phone</s> either)

      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 can see how the “manual” workflow might be preferable to some, so I’d say this app is a good rec nonetheless, thanks!

          One thing, though—I noticed East and West are flipped on the map, and I haven’t played with it enough to ascertain why that is. Is this by design?

          EDIT: I guess this orientation makes sense if I orient myself facing south and looking up, in which case east would be to my left and everything inside the circle represents what is visible to me from that time and location, right?
