Orthodox Christian Calendar for Sony's SmartWatch Extension. If you don't have a Sony SmartWatch, you should not install this application, but rather: https://play.google.com/store/apps/details?id=eir.synaxarion.en
The calendar includes the full calendar of feast and saints. It does not require internet connection, so it will display the feast, or the saint of the day, even if you are on Sinai or Mount Athos :-)
The application is solely in English and can display both the old (Julian) and the new (Gregorian) calendar (there is a setting for the Calendar style in the app settings on your phone/tablet).
Fasting rules are also displayed, but you are kindly asked not too rely too much on them, they are accurate, but you should consult your priest for the details.
Swipe left and right to navigate through days.
SmartWatch 2 only: swipe up and down to scroll through the list of saints of the day.
SmartWatch 1 only: long tap to return to the current day. Includes a SmartWatch Widget.
