What people are saying

Loved and trusted by many

Great, lightweight note and activity tracking app. I use it daily to keep track of my todo list (which I can important incomplete tasks from prior days) and as a PKM. Very snappy, too.

Stumbled into Octarine today. Excellent first impression! I'm an outliner, not a markdown guy, but appreciate the aesthetics and the app so far! Nice work!

Octarine is great, especially the latest updates made me switch from Obsidian for good 👍

+1 to Octarine. Visually more appealing (IMO) than Obsidian. "Just works" out of the box.

I love so much about this. This is everything you need and nothing you don't.

Octarine is so much better than Obsidian. With Obsidian I have to install multiple community-maintained plugins just to get basic features like text colors and highlights, but with Octarine its built in, definitely worth upgrading to the pro license as well.

I really like Octarine's purpose of having all of its features built-in. A lot of Octarine is much like how I've set up Obsidian-- except I didn't scramble for extensions that depend on each other to work

Awesome new experience. Loving it. Nice work! I am using the app daily as my go-to note app
