Evernote is one of the greatest online note taking tools. It provides more facilities such as video, audio tagging, and RTF texting in comparison with Google Keep and it is supported widely for all desktop and mobile operating systems except Linux. However, there is an unofficial application for that which is integrated nicely with Ubuntu unity called Everpad.
With installing Everpad you would be able to access to your noted, add, create, and modify your Evernote notes easily.
In order to install Everpad on your Ubuntu, you need to run following commands on Terminal.
$ sudo add-apt-repository ppa:nvbn-rm/ppa
$ sudo apt-get update
$ sudo apt-get install everpad
In addition to that you can install official Evernote application with Wine on Linux which I don’t recommend due to performance problem and/or unexpected crashes.
