Quite good

App is very smooth and functional and works very well together with the web app, which i use a ton as well, when I’m not at my phone

Good cross platform support

I needed something that work across platforms and had a good web based application. Notesnook fit the bill.

Web app is just like the desktop app. Phone app syncs and displays well.

I can use KaTeX for equations.

Minor gripe. Though it uses Markdown, it not fully Markdown compatible. Also I wish there were more hot keys for bullet points vs numbering. With the web app I need to move the mouse to select this.

Best Encrypted Note app, but could use some more editing tools!

I really like the app! I’ve been using it on my phone, ipad, and my computer and it’s been pretty nice and easy to use. It also has some of the most text editing tools based on the other apps that I tried, but I still wish there was more.

I hope at some point in the future to have more than just three fonts, maybe some adjustable text spacing, and more table customization, along with other small QOL updates.

Other than that, it is a great app and I will be upgrading my plan after using it for a little longer!
