Thanks for participating in the discussion. I have to disagree on some of your point though.

You can already download YT videos in LibreTube and NewPipe, speaking about NewPipe, I would suggest using NewPipeSponsosblock for blocking in video sponsors from creators.

I have found the download features in both LibreTube and NewPipe to be pretty unreliable. Seal always works. NewPipe x SponsorBlock is great, I use LibreTube which also has SponsorBlock built in, I just included NewPipe in the list because LibreTube breaks sometimes. But yes, NewPipe x SponsorBlock is better than standard NewPipe. BraveNewPipe is even better.

Aves Libre is a better advanced Gallery alternative with EXIF editing

Aves is a good option, it’s also available on Accrescent. Personally though, I dislike the design of the app and prefer Gallery in combination with Image Toolbox for image editing.

Aimp is a good alternative to Retro.

It’s not open-source and thus not available on F-Droid.

Spotiflyer is an alternative Murglar.

In my experience Spotiflyer has been pretty unreliable. It either pulls low quality shit from YouTube or it tries to download from Spotify and fails. So far, Murglar has worked like a dream. Just like deemix on desktop btw. You can use Deezer Premium ARLs from this guide to log in and download genuine 320kbps MP3s or even FLACs. Never had any issues.

Schildi Chat is a better alternative to Element X, its based on Element but is a lot faster and has a lot more options.

I tried it out, personally, I didn’t really like it. Element has been pretty slow for me, but I never had these issues with Element X.
