In Argentina, "Boludo" or "Pelotudo". It's very common to hear both, but the first one is like a little bit friendly, you can use it with friends and they'll accept it, but in the other face, "Pelotudo" isn't that friendly and it is regularly used to just insult, haven't found anyone that used that ironically.
I'm using Aves Libre as my gallery app in my phone, i really like it, works pretty well and looks pretty clean. It can classify the media by the apps (It need to access to the app list to do this). To watch some videos i use Libretube, but it's a shame that (i think) there's no invidious related apps in android. And the maps that i use are from OpenStreetMaps, OsmAnd in my phone. Works pretty well despite not using google services that it is pretty good in my opinion. I also use it to add some notes or interest points and then back phone contribute with that i wrote.
