Sundial is the app you didn't know you needed, showing vital info about the sun and moon any time, anywhere. Never wonder when the sun will set or rise again!
Tracking the sun and moon is something people have done for thousands of years but it's never been easier than it is today with Sundial. Sundial puts solar and lunar information into the palm of your hand and, thanks to the Apple Watch app, onto your wrist as well!
Sundial is an app designed to give everyone access to the sun and moon in ways they don't normally have it. Perfect for runners, hikers, campers, boaters, sailors, pilots, gardeners, farmers, photographers, film/tv production crew, astronomers, astrophotographers, solar installers, and travelers of all kinds. Sundial is an app for anyone who just needs to know when it'll get light and dark.
Sundial provides a one-of-a-kind display of the sun and moon's rise and set cycle over the 24-hour day. As the seasons change, the yellow Òsun is outÓ arc informs you of the precious daylight hours, shrinking during winter months and expanding as summer approaches. The white inner arc represents when the moon is visible in the sky. Civil, nautical, and astronomical twilights are also shown on the solar dial in shades of blue.
Create alerts for one of 24 different solar and lunar events and Sundial will tell you about them Ð without you ever having to open the app.
The 24 events that support notifications include:
- Sunrise, solar mid-morning, solar noon, solar mid-afternoon, sunset, and solar midnight
- Civil twilight (dawn/dusk), nautical twilight, and astronomical twilight
- Moonrise, lunar noon, moonset, and lunar midnight
- Moon phases: full moon, new moon, first quarter moon, and last quarter moon
- Astronomical seasons: March equinox, June solstice, September equinox, and December solstice
All notifications can be customized to alert you minutes, hours, and even days before an event takes place. Sundial can give you plenty of notice that you need to be ready for a sunrise, sunset, and more. Like to walk your dog for 30 minutes before dusk? Sundial can help you with that!
There's more, too!
