Sundial - Solar & Lunar Times

Tier 9 Digital
Sundial displays the sun and moon's rise/set cycle in a 24-hour ring. You can create alerts for solar/lunar events and see times for a different date or location. The Apple Watch app provides all the information available in the iPhone/iPad app, with text and graphical complications. No Internet is required to compute rise/set and other times: everything is calculated on your iPhone, iPad, and Apple Watch.

Times for dawn, sunrise, solar noon (sun peak), sunset, and dusk are displayed, along with daylight length. Moonrise, lunar noon (moon peak), and moonset are shown, along with lunar illumination and graphical moon phase. Unlike most apps, moon tilt is customized to your time and location.

Create iOS notifications for common solar and lunar events, including:

- Sunrise, solar noon, 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

There are many customization options for alerts, such as configuring a notification to be delivered minutes, hours, or even days before or after one of the event types above. For example, be notified one hour before sunrise.

You can view rise/set times and moon phase for any date using time travel: jump to a specific date or use gestures to move forward and backwards in time. Free is limited to +- 7 days from today.

With in-app purchase, you can view solar and lunar times for any location. You can search by place name, any portion of an address, or geographic coordinates. Locations can be favorited for easy reference. There are a number of settings to tweak location features, including the ability to mirror your selected location to your Apple Watch, the Today Widget, and even use for alert notifications.

Sundial is great for runners, hikers, campers, walkers, boaters, sailors, pilots, gardeners, farmers, photographers, film/tv production crew, astronomers, astrophotographers, and travelers of all kinds.

Parents, want a reminder that twilight is over and you need to get the kids inside? This app is for you. Like to take your dog on a walk 30 minutes for dusk? Sundial has you covered. Want to be notified the evening of a full moon? Piece of cake!

Religious and yoga followers use Sundial to observe special requirements. For example, Ashtanga yoga practitioners do not practice near the new or full moon. With Sundial’s powerful moon phase alerts, you can be notified a few days before the new and full moon to take rest.

Includes a Today Widget for quick access on the iPhone. The Apple Watch app includes several complications for 38mm, 40mm, 42mm, and 44mm watches.

The iPhone, iPad, and Apple Watch apps have full voice over support for all features.

Note: reported times switch between AM/PM and 12/24 notation based on your system settings.
