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)

        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?

          Attempting actually.

          (Pixel 7 running GrapheneOS 2024120200 and Skymap 1.10.04 from github via Obtainium)

            I installed 1.10.4 RC1 from the F-Droid repo (mine is just .4, not .04).

            Maybe they did something in their build to remove Google and make it work without it? You could try that one.
