12 fun home screen widgets • Apple Watch App with 100s of Complications • Create alerts for 24 solar & lunar events such as sunrise, sunset, dawn, dusk, and moonset

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

12 fun home screen widgets are available with Sundial Widgets. You can try widgets free for 3 days. Unlock forever with a one-time in-app purchase.

The Sundial Watch app gives you access to all of Sundial's solar and lunar data to go, calculated on your wrist without use of data/iPhone. There are hundreds of different complication options, including Sundial's unique time dials, solar times/countdown, lunar times/countdown, moon phase, and solar/lunar azimuth. You can trial Sundial Watch free for 3 days. Unlock forever with a one-time in-app purchase.

Sundial Watch requires watchOS 7. Supported on Apple Watch Series 3, Apple Watch Series 4, Apple Watch Series 5, Apple Watch SE, and Apple Watch Series 6.

Sundial is great for runners, hikers, campers, walkers, boaters, sailors, pilots, gardeners, farmers, photographers, film/tv production crew, astronomers, astrophotographers, solar installers, 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.

The app has full voice over support for all features.

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

Watch App is back!!!

My job requires me to know when civil twilight is every day, and this app handily tells me that. I first paid for it because I could stick it on my watch and know at a glance everything I needed to know. So I was really bummed when the developer dropped support for the watch. I could still use the main app of course, but the nerd in me really loved just looking at my wrist. I was graciously offered my money back if I wanted, but I chose not to, because I wanted to encourage the developer to keep working on this beautiful app and, as a software engineer, I know how these things go. And now I am SO HAPPY to see that not only is the watch app back, but back with a vengeance! The configurability of the widgets and complications is just stunning. The only downside is that now I’m going to be fiddling with this for weeks in order to find what arrangements are “just right” for me. Thanks so much for standing by your product and its continued improvement.

Excellent Info in a Beautiful, Clean Design

In my quest (I’m a librarian) for an app that would display daily and monthly solar and lunar phases, I did a little research and found this one was very well-rated over and over for its breadth of data, its friendly interface, and its features. Since this app kept floating to the top, I downloaded it and I have been a Basic user for a few months.

I just love it, and I find myself using it often. It is deceptively simple, due to its clean design, but packed with information, which I enjoy browsing. Some practical uses:

• I like to know when the full moon is coming up for viewing (and sometimes to confirm a string of bizarre behavior, although that seems to have ramped up to “daily” in 2020).

• When we’re working in the yard, it’s great to see how much daylight we have left.

• When we’re traveling and want to view a sunrise or a sunset, we can see the time for that, no matter where we are in the world.

• I have a daily alert set for dusk, to remind me to bring in our suet and birdfeeders, before they are accosted by marauding raccoons from the woods.

• The app is also a terrific learning tool, both for us, ourselves, and for us to use as we help introduce our 3-year-old granddaughter to these natural, ancient rhythms and phases.

Very pleased - a great app. I plan on upgrading for more personal tinkering and preferences. Highly recommend!

My favorite complication; exceptional developer

The best visualization of sun and moon data you’ll find on iOS (and watchOS), or anywhere else. The unique dial is such a clever, concise infographic, simple to read and dense with information. It’s glanceable, memorable, and legible even at the scale of a watch complication. The update to v7.0 is fantastic: it introduces a brand new watchOS app with extremely deep customization, as well as the longest list of complications and iOS 14 widgets I’ve seen from any app, period. Best of all, the developer is very committed to the project and extremely responsive to customer support, and just a friendly, pleasant individual to correspond with. Sundial may not be the most “mission-critical” app on your phone, but if you’re the kind of person who looks skyward — and at app reviews — then this is more than worth the price of a coffee.
Enjoy! 🌞🌝
