Sundial+ across Apple devices

TL;DR

Track daylight and moon phases, catch golden hour, and wake at sunrise. Get alerts and widgets for iPhone and iPad, plus a full-featured Apple Watch app with hundreds of complication combinations. Ready for iPhone Duo.

Overview

Sundial+ provides a one-of-a-kind 24-hour display of the rise and set cycles of the sun and moon. As the seasons change, the yellow “sun is out” arc shows your precious daylight hours, shrinking in winter and expanding as summer approaches. The white inner arc shows when the moon is above the horizon.

Create alerts for 36 distinct solar and lunar events. Customize their timing, sound, image, days of the week, alarm mode, and more. Sundial+ also includes 40+ Home Screen and Lock Screen widgets for iPhone and iPad, along with a comprehensive Apple Watch app offering hundreds of complication combinations.

Sundial+ is all about making it your own. Choose the data you see on the app's home screen, give an alert its own emoji and custom sound, pick which solar events appear in a widget, or put together the perfect set of complications for your Apple Watch face. Customize it to fit your needs and the way you spend your day.

Background

Sundial+ is the evolution of Sundial, an app I first released in 2015 (!!!). It's rebuilt from the ground up for today's Apple devices, including iPhone Duo.

Headline new features include support for golden and blue hour, configurable app home screens, support for 28 languages, and more customizable alerts with alarms and custom sounds. Most Apple Watch complications and widgets are now configurable, giving users even more options. And of course, there's an experience tailored to iPhone Duo. See the full list of improvements.

The new codebase provides a solid foundation for future improvements. I have a huge backlog of new features I can't wait to work on.

App Store Description

Sundial+ alert settings and notification example

Sundial+ puts sun and moon timing on your screens and wrist with customizable alerts, 40+ Home and Lock Screen widgets, and hundreds of Apple Watch complication combinations.

People have tracked the sun and moon for thousands of years, but Sundial+ makes it easier than ever. It puts solar and lunar information in your hand and, with the Apple Watch app, on your wrist.

Sundial+ is perfect for runners, hikers, campers, boaters, sailors, pilots, gardeners, farmers, photographers, film and TV crews, astronomers, astrophotographers, solar installers, and travelers of all kinds. Sundial+ is for anyone who needs to know when it will be light and dark.

Sundial+ provides a one-of-a-kind display of the sun and moon's rise and set cycle over the 24-hour day. As the seasons change, the yellow "sun is out" arc informs you of the precious daylight hours, shrinking during winter months and expanding as summer approaches. The white inner arc represents when the moon is visible in the sky. Civil, nautical, and astronomical twilights are also shown on the solar dial in shades of blue.

Create alerts for one of 36 different solar and lunar events and Sundial+ will tell you about them without you ever having to open the app. Alerts can take the form of a notification or alarm. Alarms break through your mute/silence setting and focus mode, perfect for early risers.

The 36 events that support alerts include:

  • Sunrise, solar mid-morning, solar noon, solar mid-afternoon, sunset, and solar midnight.
  • Golden hour and blue hour (morning and evening).
  • Civil twilight (dawn/dusk), nautical twilight, and astronomical twilight.
  • Moonrise, lunar noon, moonset, and lunar midnight.
  • Moon phases: full moon, new moon, first/last quarter moon, and waxing/waning gibbous/crescent moon.
  • Astronomical seasons: March equinox, June solstice, September equinox, and December solstice.
  • March Equilux and September Equilux: the days near each equinox when daylight is closest to 12 hours at your location.

Notifications and alarms can be customized to alert you minutes, hours, and even days before an event takes place. Like to walk your dog for 30 minutes before dusk? Sundial+ can help you with that!

TIME TRAVEL

Use Sundial+'s 24-hour wheel to see where the sun and moon will be today, tomorrow, and any other time you choose. Use gestures on iPhone and iPad to scroll through dates. Or jump to a specific date with iPhone, iPad, and Apple Watch.

WIDGETS

Sundial+ features 40+ different Home and Lock Screen widgets. Most are customizable.

APPLE WATCH APP

The Sundial+ Apple Watch app makes all of its solar and lunar data available where it's most easily found - right on your wrist. Because Sundial+ runs on your watch, you won't even need to have your iPhone with you.

Hundreds of complication combinations mean you'll find one that displays the right data and has the right look - even for the most customized watch faces. Sundial+'s unique time dials, solar times/countdown, lunar times/countdown, moon phase, and solar/lunar azimuth are all present on Apple Watch.

ACCESSIBILITY

We want to make sure everyone can enjoy Sundial+, which is why we built in full VoiceOver support from the ground up.
