Then one day I started using Apple Notes to start a journalling practice and then I realised I could use it for just about every other thing that I was using all these pieces of software for. I now use it and a calendar exclusively and it handles my todo lists, my random thoughts, my personal relationship management, my checklists, pretty much all the things that are actually important to me. The reason I prefer this over a single text document is simply because I can categories my files into folders. That's it. Same thing could be achieved with text files and folders but I like having this synch on all my devices.
Plain old text is amazing in its simplicity and power.
Someone once left a comment on a Zettlekasten thread and it's something I've always thought about now whenever I get the itch to complicate my system. [1]
"I had the realization yesterday while waiting for a train that the Notes app on iOS contains all the functionality I'd need in order to be able to build a small organization/business .. as long as I standardized my form of note-taking and rigorously applied policies on how Notes are transformed from one Folder to the other"
And I find this applies in my personal note taking life as well.
