Description

Sundial displays the sun and moon's rise/set cycle in a 24-hour ring based on your current location.

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 for moon aficionados, along with lunar illumination and graphical moon phase. Unlike most apps, moon tilt is customized to your time and location.

You can 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.

Sundial does not require an Internet connection to calculate rise & set times or to schedule notifications: GPS and built-in algorithms are used. Sundial does not use any mobile data and is very conservative about battery usage.

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.

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.

You can enable one alert for free. Unlock unlimited alerts by making a one time in-app purchase of Sundial Premium. Premium has other neat features including options to backup and synchronize your alerts to other devices using iCloud and disable screen lock when Sundial is active (use it is a clock on your desk).

Includes a Today Widget for quick access on the iPhone and an Apple Watch app. 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.

Great app for runners, hikers or walkers.

I like to time the start of my runs so I am running when the sun rises. Gives me a boost of energy when the sun come up. Sundial makes this very easy to do. Plus the app is internet free; there is no backend server keeping track of your personal data. Also Sundial is easy on your battery. Alerts are very useful. Sundial is better than any of the other sun rise/sun set apps I looked at. Respect to the developer.
As others have suggested, please consider adding some form of first/last light. I’m not sure what makes the most sense; civil or nautical or astronomical.

Thanks Cooooooooper! Version 4.0 has dawn/dusk on the main screen now. And twilights is an option on the solar dial. Cheers.

Wonderful App! Nothing else like it 🌞🌝👍

Thank you so much for this app!
I've been searching for something like this for years. A simple, visual representation of of the setting and rising of the sun and moon. Rather than just listing times or showing the common "sine wave" type graph, it shows the information on an intuitive 24 clock face. It's like a fancy complication on an expensive watch.
Almost makes me want to get an Apple watch so I can have it on my wrist.
I would gladly pay $5 for this, but it's free!
Suggestion: the widget should have the same clock face as the app, just smaller.

Howdy! You may have seen this, but in a recent release I added the dials to the Today Widget for larger phones. Cheers.

Amazing app! For our hens and for us!!

I was looking for something that allowed me to put the hens to bed in the evening, and then get a good nights sleep, as well as wake up just before sunrise when the hens started squawking that they wanted out into their day pen. The fact that this app offers not one but all three twilights, a.m. as well as p.m., has me over the moon in love with it! I can let the hens out at morning civil twilight, put them to bed at evening civil twilight, and then set the last alarm for nautical twilight to get a wonderful night sleep, in tune with my body and the rotation of the earth :-) LOVE LOVE LOVE this app

Developer Response ,

Love your use of the app ZebraBus!! I am always fascinated at how people are using the alarms. Thanks so much for the review.
