iOS: Following on a recent update for the Mac version, note-taking app Evernote has updated its iOS version today with a similar overhauled interface. The new look and feel emphasises speed and efficiency, and it's available right now for iOS devices.
Now, you can easily create new notes with a single tap, reorganise everything to suit your needs, and track your unified notebooks easier. Overall, everything in the app is only a couple of taps away so you can get to your notes quickly and easily.
