Wake up with the sun. Never miss golden hour. Sun Alarm turns sunrise, sunset, and other sun and moon events into reliable daily alarms — at any place on Earth. **Set alarms for natural events** • Sunrise and sunset • Solar noon • Golden hour and blue hour (morning and evening) • Civil, nautical, and astronomical twilight • Moonrise, moonset, and moon transit • Moon phases: full moon, new moon, first quarter, third quarter, crescents, gibbous • Custom sun altitude (e.g. “sun 5° above horizon”) • Next equinox and solstice **Flexible timing** • At the exact event time, or any number of hours and minutes before or after • Alarms follow the event every day (or next occurrence for moon phases and equinox/solstice) **Any location** • Choose a place on the map or search for a city • Correct time zone for the chosen location, so alarm times stay accurate when you travel or when daylight saving changes **Designed for daily use** • Multiple alarms, each with its own type, place, and offset • Optional names • Snooze and clear from Lock Screen and notifications SunAlarm uses your chosen location’s coordinates and time zone to compute event times, so you get one less thing to think about—and one more reason to look up at the sky.
