I use multiple note-taking apps. I use Obsidian for "learning". It's ability to connect thoughts and capture what I'm reading and learning is exemplary. I use Apple Notes for "quick". It captures things on the fly that I don't want to think about too much. To dos, read laters, groceries to share with my husband. And I use Notion for "specific use cases", like tracking and publishing my golf adventures this summer! While many people assume one app should be able to do everything, I find having individual apps for different purposes helps me mentally adjust to the task at hand. Each has it's own place. I appreciate your descriptions of how each works for you!
