Boostnote is the best note

As a developer frustrated with traditional note taking apps I once made a list of features that I wanted from a note taking app with the expectation that I may eventually have to write such an application myself. What I wanted was the ability to write my notes in markdown and search through them rather than manually organize them. Boostnote does this and more.

I’m Rating This Because It Deserves It

Open source cross platform markdown note taking. This sounds like a crazy sentence to most people, but to a programmer and someone with awful short term memory but slight OCD, this is amazing. I want to find it again just to experience this feeling again. Lol it’s really good though for real.

The Great GoldenJoe ,

Glad to finally have it!

Love this tool on desktop. It will be handy to have syntax highlighted notes on my phone.

Developer Response ,

Thanks for the comment! But we still need to implement lots of missing features. If you have something in your mind, please submit an issue to our Github repository!
