So a friend of mine recommended Obsidian ages ago and I looked at it but thought I was happy using Joplin (another text-based note tool) which I still think is a great app. Took a brief look at it and thought it was just too complicated...
Then recently, I went down a youtube rabbit hole watching videos of how people use Obsidian... OMG 🤯
Now I have 2x Vaults, one for work and one personal. Dataview, templater, quickadd, periodic notes have just changed everything. Now I have documents for each person at work with their basic info and then when I make a meeting, I can just tag them which then updates a dataview table that shows what meetings I've been in with them.
Tasks allows me to just create a bunch of todos in random notes and then I can create a table to show all my undone tasks.
I mean, why did I wait so long? I've been using it for about 10 days now and it's been such a game changer. Sorry Joplin.
I've been using Syncthing to sync my notes... it doesn't work on my iPad (because of the way the iPad file permissions work) but I'm able to sync between my phone and my personal computer and work computer. (I also have Syncthing running on my NAS so it's automatically backed up!!)
Syncthing doesn't cost anything. You could also use dropbox or google drive or whatever so you don't have to pay. I agree, it's a pretty steep fee for what it is.
