I might be a little jaded and expected this to be a clickbait article, but it actually is a great list and I can personally recommend Mullvad, Syncthing, and Aegis Authenticator. Well done Android Central and Harish!
One change I might suggest is KeePassXC (and specifically the Keepass2Android app). If you're already set up in the Syncthing environment (or even Dropbox or other sync system), this is a no brainer. Everything I've heard about Bitwarden is positive, but if you Trust No One, KeePass is the way to go.
