About Icon


Outdoors people need to keep track of daylight. Pilots need to know when to turn on lights and log night flying.

Civil Twilight for Watch finds your location, and calculates the sun position without going out on the internet like the other apps. Anywhere in the world! In your plane, on your boat, out on a hike! This is self-contained on the Watch and doesn't need the phone nearby either! Accurate to about a minute through the year 2050. For many more features, including sun rise and set times for other dates and places, check out our iOS app "Civil Twilight Calculator" on the App Store.

Complications fully supported. There is now a Setting View to select which time to display in complications. Swipe left to change this Setting. As space inside different complications allows, some complications have both rise and set times and even a sun arc for daylight! Small complications allow a single user-selected time, like "C up arrow" for next Civil Sun Rise.

This App is for Apple Watch Series 3 and later!
