Libretube for YouTube: https://f-droid.org/en/packages/com.github.libretube/
Organic Maps for navigation and stuff: https://f-droid.org/en/packages/app.organicmaps/ It even shows speed cameras, which Google doesn't!
Seal for downloading videos: https://f-droid.org/en/packages/com.junkfood.seal/
Yes, Aegis is the best TOTP app. I recently switched from Authy to Aegis and it is pretty good.
Haven't tried it yet myself, but I've heard that Organic Maps is much smoother and faster alternative to OsmAnd~.
Fair Mail works way better for me than K9
I find FairMail better suited for my needs, too, but both are great e-mail clients with extensible customizability. It is up to your preferences, I suppose.
I would love to use Lemmur, but I've been unable to add the lemmy.ca instance to it. It just says "Instance not found"
You're better off switching to Jerboa, that's what I did. Lemmur is no longer in development.
I got the qrcode app since I needed one, cool one. And I also use K9-Mail really good client imho
Just recently found Barista. Its an alternative instagram client that lets you browse privately and does not expose you to their stupid algorithm. Also Infinity to go on Reddit.
It's called Barinsta in case anybody is looking for it:

Development has stopped, not working anymore because of expected Meta lock-in.
