App Store Description

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 “sun is out” 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 – 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 around dusk? Sundial can help you with that!

There's more, too!


Use Sundial's 24-hour wheel to see where the sun and moon will be today, tomorrow, and any other time you choose. Use gestures on iPhone and iPad to scroll through dates. Or jump to a specific date with iPhone, iPad, and Apple Watch.


Sundial features 15 different widgets that can be used to put its data right onto your Home screen.


The Sundial Apple Watch app makes all of its solar and lunar data available where it's most easily found – right on your wrist. Because Sundial runs on your watch you won't even need to have your iPhone with you.

Hundreds of complication combinations mean you'll find one that displays the right data and has the right look – even for the most custom of watch faces. Sundial's unique time dials, solar times/countdown, lunar times/countdown, moon phase, and solar/lunar azimuth are all present on Apple Watch.


We want to make sure everyone can enjoy Sundial which is why we built in full Voice Over support from the ground up.


We believe that your data is your own. That's why Sundial does't collect any information about the people who use it. Sundial does not store your location or upload it to any third-party service.

Because of its advanced features and the use of Apple's latest APIs, Sundial Watch requires iOS 14, iPadOS 14, and watchOS 7.

Sundial is a free download with some additional features requiring an in-app purchase to unlock. All offer a three-day trial before any payment is taken.

- Sundial Widgets unlocks all 14 iPhone and iPad Home screen widgets.
- Sundial Watch unlocks the full Apple Watch app, including hundreds of complications.
