Sundial is the app people don't know they need, showing vital information about the Sun and Moon any time, anywhere.

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 the hand and, thanks to the Apple Watch app, onto the wrist as well!

Sundial can proactively notify you when a solar or lunar event is about to occur. Alerts can be configured and personalized to meet a user's needs.

What is Sundial?

The centerpiece of Sundial is it's 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.

Alerts for 24 different solar and lunar event types are available and Sundial's notifications will make sure people don't miss them – they don't even need to open the app to see vital information.

The 24 events that support notifications include:

Every notification can be customized to appear minutes, hours, and even days before the event takes place. Someone likes to walk their dog 45 minutes after sunset? Sundial can help with that!

Who is Sundial For?

Anyone who needs to know what the Sun and Moon are doing at any point in time, including the future.

People who would benefit from using Sundial include:

We feel strongly that there are people out there who could benefit from using Sundial but don't yet know it.

Features include

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

Hundreds of complication combinations mean everyone can 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.

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