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 and iPad.

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.

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.

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.

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

Gps and saved location notifications

Brilliant app, downloaded yesterday with premium features, I have the widget, main app and Apple Watch gps set to always, GPS location street address on Apple Watch and iPhone is mainly inaccurate but a brilliant feature and usually shows I’m at my neighbours address even though I’m at my home address,I have notifications set up for GPS and saved locations but only GPS notifications come through and nothing for saved locations, this can do with fixing

Thanks the alerts helps alot ,

Very good Application

It helps a lot to us
It would have been better if for the app alerts it had a custom period of time before and after and not only fixed 15 /30 min
Also it would be better if it will have an option in alerts to choose if the minutes before or after the events will be equal minutes (60 min for an hour in 12hours days) or real minutes depending on the length of the day.

Developer Response ,

Version 4.0 just released has a new "Premium" in-app purchase. Once unlocked, you can set the offset to the minute and are not bound to the fixed list provided in the free version.

Subtle tweaks greatly improve an already brilliant app

I have favoured this app from the start, my only grievances of the early versions being the absence of twilight alerts and displays (I’m an amateur astronomer). Earlier updates added the alerts. This latest update has perfected the exquisite visuals by adding in the twilight zones to the dial. Thanks so much 😁.
