If you have recently switched to Ubuntu from Windows/Mac and you used to to keep your notes in sync with Evernote, then you might be missing the feature-rich note taking application on Ubuntu. There is no official Evernote application for Ubuntu, but you can use another application, smartly-named Everpad by its Developers.
now, install :
Everpad is an easy-to-use application which also comes with a app-indicator, so you can create/manage notes from the task-bar. To keep your notes in sync with your Evernote account, you need to authorize the application, for which there is an option in the Settings and Management menu. Once authorized, Everpad will automatically synchronize the previous notes in your account with the local notes.
Using the simple and clean interface, you can easily create / manage notes and organize them into notebooks. The Editing Interface is simple and icon-based, you can create to-dos, add image, link, and other items just like the official Evernote Application on Windows / Mac.
The best thing about Everpad is its app-indicator which sits right in the taskbar and helps you quickly create new notes or manage the existing ones.
If you don't want to use Everpad for some reason, then there is no other alternative which comes with Evernote sync feature. You can use Tomboy Notes and use its sync feature to save the notes in your Dropbox folder, this will automatically sync your Tomboy notes with Dropbox.
