Take a little of the Klingon home world with you wherever you go! KlingonCal shows you the Kronos equivalent of today's Earth date on your iPhone or Apple Watch.

KlingonCal lets you keep track of today's Earth date on the Klingon home world with an iOS 14 widget on your iPhone, or directly on your Apple Watch face. The app can display the date using English or Klingon characters, and a date calculator shows you Klingon dates for any Earth day you specify.
