Can't really choose what app to use, though. My go to choice for now is a vim and plain text file. But I'd love to have iCloud sync + smart features (like grepping over todos) out of the box. I use Obsidian for the second brain, and it looks like a great choice for interstitial journalling, but their app is an Electron :( Apple Notes seems like a great choice for iOS/Mac, but close source and I can't even find an easy way to automatically insert time. Notion is a great thing too for this, but, again, too web based.
