What people are saying

Loved and trusted by many

Octarine is my new favorite daily planner, knowledge base, and journal. Everything works intuitively right out of the box, so I can spend my time writing instead of worrying about creating some theoretical perfect setup.

After testing upwards of 75+ apps, I settled on Octarine. From my personal needs matrix, Octarine was the only app that checked all my boxes aside from missing iOS apps. I love this app!

Just downloaded the free version - the first PKM that I am already blown away by! Cannot wait for all of the features in the roadmap!

For anyone considering trying Octarine… I don't regret spending the $50 in the slightest. Really… $60 is a total deal too.

Been an early adopter of Octarine and have used it daily ever since. Octarine is a delight to use! Lightweight, beautiful, highly performant!

I rely on the Octarine app every day. I use it to jot down my daily plans, sprint plans, and project checklists before I start working. Having a tool that's so easy and intuitive to use really reduces a lot of friction in my workflow. This is truly the next generation of note-taking for developers.

Been using Octarine as my daily driver for the past few days and I'm impressed. Seriously considering jumping from Noteplan.

Combination of simplicity and functionality is what makes it such a great tool. With Logseq and Capacities I find myself spending too much time on "the system", with apple notes I am missing key features, Octarine is the perfect middle ground that allows me to do what I need efficiently.

Hey, i came here to say this implementation of an obsidian type note management app is CRAZY GOOD. Damn.
