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 24 solar and lunar events:

- 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

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.

A 3 day trial of unlimited alerts is included. Purchase Sundial Premium via one-time in app purchase to continue receiving alerts after your trial has ended.

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 Premium also unlocks reporting of solar/lunar altitude and azimuth (direction).

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.

Sundial Premium is a one-time in-app purchase that unlocks:

- Unlimited alerts (free is limited to a 3 day trial); alerts can be backed up to iCloud and synchronized to your other devices
- Unlimited time travel (free is limited to ±7 days from today)
- Jump to another location. Recent and favorite locations can be backed up to iCloud and synchronized to your other devices.
- Turn off screen lock (use Sundial as a clock at your desk)
- Customize the dial
- Many additional settings related to location
- Remove the coin jar button on the home screen and occasional Sundial Premium reminders

A Pleasure To Use

A beautifully designed app! Really raises your awareness of the solar and lunar cycles in nature and your daily life. There are so many possible alert settings and really original alert sounds. A great app for the photographer who wants to take long exposure shots of a lake on a moonlit night; for the sunlover who wants to sunbathe exactly, say, 45 minutes after the mid-morning sun but before the hot midday sun; for the gardener who wants to shelter precious exotic pot plants from sunlight during the hottest time of the day. At the risk of sounding corny, the app seems designed with love and real enthusiasm. I just updated it to the latest version for a few dollars.

Bit disappointed.

Bit disappointed really, started using the app earlier this year and loved it! Except now you’ve added a premium feature which is fine for those who want to access all the new bells and whistles, but now I can’t even do the things I was already doing with out signing up... most annoying thing is alert limits. I can only have ONE now unless I switch to premium? Atleast let us have 2 or 3. Bit ridiculous tbh.

Internet Connection

If an internet connection is not required to calculate info, why does the app pester you to turn location services and notifications on ??
My iPad doesn't leave the property. I think you ARE on-selling the data you are harvesting.
Why not have the ability to enter a lat & long ??

Developer Response ,

Hi thomatis. In a future release I plan on providing a way to enter location manually. Please google me, the developer, Mike Muegel. I do this as a hobby project and do not collect ANY information (privacy policy
