Ok basically what the title ask. There are so many note taking apps available and also the good old notepad, but, how do you take notes? What do you actually take-keep notes on? Is it like complicated things or simple ones?
All time times that I started using an app or a pen and paper intended up just using a simple reminder for things. Others I just remember.
Trilium is nice because it runs local first but also has the server side to sync too and work as a web app. Meaning I can access it anywhere and on my phone. I run it on docker on my server then on Linux on everything else.
I run memos on docker on my server as well as a web app. There is an iPhone app MoeMemos but they don’t have offline use yet. Good thing about memos over my notebook is that I can easily tag and search things. Bad thing is my server goes offline and I’m not home then I don’t have those notes. Good thing I send backups to other servers every 10 minutes.
Some other tools I use which might be interesting to you include Paperless-ngx for organizing and tagging PDFs. I use Zotero for work PDFs though because I need the exact citations. I also use Nextcloud to sync my files across devices to make sure the 1000 of notes and PDFs are backed up, though trilium backups well already.
I have had fights with Nextcloud in the past but somehow I got it working well this time. Only using it for syncing though none of their other crap.
I also know of Joplin which like Logseq has offline app note taking on all devices.
