## What is ScopeClock?

ScopeClock puts every number you need to set up a computerized telescope on one handy display and helps you plan tonight's observing while you're at it. Can you always remember your UTC offset, or whether daylight saving time is in effect? ScopeClock can.

Everything at a glance:

• Night Dial — a 24-hour dial of daylight, twilight, darkness, and moon phase
• Local time and date in 12- and 24-hour formats
• UTC time, UTC offset, and daylight saving time status
• Julian date and sidereal time
• Sunrise and sunset, astronomical dawn and dusk
• Time and duration of true darkness
• Moon phase, moonrise, and moonset
• Latitude, longitude, and altitude

Widgets for your home screen and lock screen show the Night Dial, sunrise, sunset, darkness, and moon phase without opening the app.

Night vision mode turns the display red, so checking your times never costs you your dark adaptation.

ScopeClock works completely offline — out in the field you can still get everything you need!
