errata: thanks to Cedric for pointing out two other big cons with Notesnook: no spell check on Android and no support for frontmatter - 2023-10-28

Notesnook is a privacy first, zero knowledge, and open source app for Android that is well designed and easy to use. It has almost every feature you could want in a note-taking app and then some.

It could be one of the best apps but it needs a few fixes. I really enjoyed testing it this week and to learn that they're going Open Source during the same week that I was doing my review was simply bonus points for them!

At $6.99 per month for the Pro version, which I didn't try, you can export to Markdown, HTML, PDF and attach images. That's a bit steep and the fact that the editor seems a bit buggy means that I am going to keep a close eye on this one. If you're into playing with apps, do check it out!
