There is always emacs with org-roam.

Org-roam is kind of a wiki, you write your notes with all the formatting power of an org-file and you can link to other notes you have written.

Of course everything is searchable, with tags, without tags, however you want.

BUT: it takes time to get used to the shortcuts, and it takes a lot of time to configure everything how you like it.

The result is worth it.

Edit: I use Nextcloud to sync my notes accross my devices. On the smartphone there seems to be the App OrgNote available, but I haven’t checked it out, as I don’t use my smartphone that much.

“Microsoft is an evil company, basically the enemy of free software, but here is why you should use their product…”

With this kind of budget there has to be a better way to organize data and permissions. They have infinite money and a lot of smart people at their company… And I am starring at poor quality icons and the most confusing structure I can think of.

As a german it is beyond me how this software got so popular. But businesses love those user nightmares. I recently had to work with Teamcenter from Siemens - nope nope nope nope.
