Zoho notebook

I'm a huge fan of the classic pen and notebook. But it's a shame if I didn't try digital note-taking. So, there's a lot of nice things going on with this app. But my all-time favorite is its notebook feature. Ok, some apps had labels or folders, but the interface is boring. With this app, you can create notebooks to classify your notes. You can change the covers of the notebook( their covers are artsy), lock it ( or make it accessible), and access it on other devices.
