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/September equinox and June/December solstice. - Spring and fall equilux. 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! There's more, too! 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.
