Clock widget originally designed for the Fairphone 2.
The Fairphone Clock Widget was the default clock in official Android 5 OSes for the Fairphone 2 smartphone, both Fairphone OS and Fairphone Open.
It's just a regular clock widget. It doesn't include other Fairphone 2 goodies like battery estimation, "Your Fairphone for..." or Peace of Mind info, for the moment.
Fairphone stopped the development of some Fairphone-specific apps when the Fairphone 2 was updated to Android 6 "Marshmallow". Since they are open source, the WeAreFairphone community make them available for those users who want to keep the original Fairphone experience.
You may want to take a look at Fairphone's Recent Contacts widget and Fairphone Launcher 3 too.
