I know these apps but none of them is as good as standard notes in my opinion. Notesnook seems fine but I don’t like fact that it is based in Pakistan. I used Joplin before buying a sub for standard notes so I know it.
Currently I have also subscription on Crypt.ee for photos but there is also a notes app integrated. Maybe I’ll start using it. Developer of cryptee was very active on reddit and he seems like a man who values privacy and security.
But I hope that simply proton will not force the migration of standard notes accounts to proton accounts and for old users everything will be as before.
And there is orgzly for linux or something?
