Notesnook app is what Evernote should have become long ago. And they're still improving.

I work in content writing and communications. My day starts and ends in Notesnook. My Chrome app is always open; it's where I take all my notes. The clean design, Focus mode, the tagging and color coding are all features that help keep my work organised every day.

This app is really great so far! (using the android version currently) looking forward to maximizing the **** out of this. Also i think you should mention off the bat that unlimited storage in the pro version means file upload (pics, etc).
