I like Joplin

I'm gonna be that guy:

Org-mode with emacs. Sync with syncthing.

There are mobile client too.

I used Joplin for a while but it kept giving me these weird errors when writing accents (half my notes are in Spanish...), so I switched over to Zettlr. It’s now where I take notes for everything.

However, those notes haven’t been synced between devices because I haven’t successfully set up my Nextcloud server in my Raspberry Pi. That’s why whenever I need synced notes, I still use my phone’s default note app, since it syncs automatically...

I am using Joplin on Desktop and Android

I use CherryTree and Xournal++ on desktop, and Scarlet Notes on Android.

https://www.qownnotes.org/ Together with a self-hosted Nextcloud instance.

I am testing out Obsidian at the moment and I am liking it. I am still trying to figure out what the best way to sync between devices. At the moment I have found this script and Syncthing, but I am still only using it locally. Their phone app is still in closed beta, so probably not the best choice if you want to access notes from your phone.

Check out Logseq, or Obsidian, or Zettlr. They all use markdown as their base meaning you can transfer your notes anywhere if you don't like the development of the app in the future. They all can be hosted on a Seafile instance which is a really good Delta-sync app that has encryption. I use Luckycloud.de (seafile), which costs me 1 euro a month.

Check out stick - shareable git notebooks. There is a web UI and you can edit the files via standard git commands locally or via SSH when you're at a PC. This is a project I created.

My enterprise-grade notes setup:

mkdir ~/Documents/Notes
cd ~/Documents/Notes
$EDITOR name_of_note.txt

For lecture notes, I do this:

$EDITOR "$(date +'%Y-%m-%dT%H:%M:%S%:z').md"

I don't actually type out commands like these; I have alises for them. I sync my notes with git, so I don't have to learn another tool just for notes.

you can host your own standard notes, can't you?

There's a whole subculture of people obsessed with Emacs' org-mode for notekeeping, todos, agendas, etc. I don't really know the half of it, but what I appreciate is the outline view, inline LaTeX and code snippets, nice tables, and export to HTML. Then I use Syncthing.

Syncthing + whatever apps you like. I like vim or typora on desktop, and Markor on android.

I’m using notion.so for advanced content like tables, pictures and so on...

 Notes for handwritten notes, I sometimes password protect sensitive notes, plus it’s synced with all my devices

if you don't mind using an electron app, and don't want to pay for the service, and want some privacy with an all-in-one notes tool, then https://www.getoutline.com/ is probably your best pick. it is essentially a self-hosted open source version of https://notion.so - personally i use notion as i can't host my own server reliably (they have a paid option, but the free works perfectly fine if you aren't intent on organizing wikis with large teams).

but as much as it pains me to say for my personal use, i am in the process of switching back to evernote (using the nixnote2 client), as the growing numbers of electron apps on my system are essentially making my computer move at snail speeds (they are massive resource hogs). nixnote2/evernote is definitely not good enough for me and i do prefer my privacy and FOSS, but there just aren't any non-electron live sync note apps available that will work with all mine and team's devices (linux, windows, ios, android). as i share my notes with a small team and there just aren't any options out there for my needs bare nixnote2/evernote (which is not good enough by a long shot, as i actually need faster sync and live collaboration (and preferably encrypted), but for now, it's the ONLY option i can use, and i hope some day there will be a fast non-electron all-in-one notes app with live collaboration outside of the apple ecosystem).

I use the Vivaldi Browser, which includes a note editor (Markdown) as one of it's multiple functions. The browser is very privacy oriented and with a own Sync encrypted end2end for all data, also the notes.

I use QOwnNotes on my desktop that syncs to my NextCloud for keeping text based notes. For more feature full notes with reminders, checklists, etc I use Google Keep. Tried Apple Notes but it lacks some features on the web browser access and is only fully functional on iPhone, iPad and a Mac.

Regarding OpenSource, which of course I also prefer, but generalizing this with non-private is a serious mistake. There are also FOSS services and applications that point directly to Google or include APIs from large companies, and proprietary soft that does not. If you are not a programmer or even if you are, having an app code with millions of lines is going to be difficult, if not impossible, to check everything. As you can see, it is also considered proprietary soft, although only 5% is protected but auditable and the rest OpenSource. Extremism is seldom a good counselor.

Note Crypt Pro, my personal recommendation, underrated. No cloud features though, just a bunch of local encrypted note text files.
