From the guys who make sharing notes between iOS, Android, and your desktop computer simple:
We’ve been beta testing new versions of Simplenote for Mac, Android, and iOS 7. They look a lot different: cleaner, simpler, and more lightweight. Our approach was to return to first principles and build anew.
A side effect is that some less frequently used features won’t be available, at least at first. Some people will cheer. Others, like those who adore sorting notes by reverse chronological creation date, may mourn. More details are coming soon.
Also of note are improvements to Simperium, which should make syncing between your devices faster and more seamless.
