I made Really Simple Notes after getting frustrated with other note-taking apps.<p>I found that I was spending more time formatting my notes than writing them. I like the sidebar navigation that Coda provides, but I hate how slow Coda is. I like how fast Google Docs is, but I don't like knowing that all my data goes to their servers; who knows what they are doing with my data?<p>That's when I decided to create Really Simple Notes. It's an offline-only, no-formatting notes app with a sidebar to navigate notes.<p>I've found that as I use it for personal notes, my productivity has increased significantly. I'm no longer fretting over formatting or waiting for things to load. I'm just writing notes.<p>The app is totally free, so I hope you'll give it a try!
+1 for plain text.<p>I really like Notational Velocity/nvAlt because it's a fast way to search/edit nodes. However I was always fighting with the text formatting, which got in the way.
