Skyclock is an Android lifestyle app that calculates sunrise, sunset, and twilight times based on your location. It is useful for pilots, photographers, golfers, hunters, construction managers, and anyone who enjoys outdoor activities and wants to plan their day around natural lighting conditions. With Skyclock, you can see the usable twilight and plan your outdoor activities accordingly.

The app has an analog clock face that can be set to either 12 or 24 hour mode, and a patented 'slice of pie' display method, which enables you to quickly see and understand all of the different times. Skyclock is all about convenience, planning, and safety. You can plan your outdoor activities to take advantage of natural lighting conditions, such as finishing landscaping jobs, timing your run to end before full dark, or fishing or hiking when the light is just right.
