Sunwise: Sun, Moon & Time

Sunwise shows sunrise and sunset for any day and any place, every stage of twilight, golden and blue hour, and the moon. It also keeps network-synced atomic time on a watch dial. Everything is calculated on your phone, with no account, no ads and no tracking.

TODAY AT A GLANCE
• Sunrise and sunset with bearings, day length and the change since yesterday
• The sun's path through the day, drawn against the color of the sky
• Solar noon and the sun's highest point
• Polar day and polar night handled correctly

TWILIGHT AND GOLDEN HOUR
• Civil, nautical and astronomical dawn and dusk
• Blue hour and golden hour, morning and evening
• A twilight timeline that shows where the light goes

COMPARE TWO DAYS
• Put any two dates side by side, like October 1 and today
• See both sun paths, both twilight timelines and every difference: sunrise, sunset, day length, solar noon and sun height

THE MOON
• Phase, illumination, moonrise and moonset
• Next full moon and new moon

THE WHOLE YEAR
• Daylight through the year in one chart
• The longest and shortest day for where you are, in either hemisphere
• Equinoxes and solstices with countdowns, midnight sun and polar night

ATOMIC TIME
• A built-in time client syncs with an NTP server you choose (pool.ntp.org, Google, Cloudflare, Apple, Netnod or your own)
• See how far your phone's clock is off, to the millisecond
• Choose an analog watch dial with a 24-hour sky sub-dial, or a digital readout

SUN COMPASS
• Where the sun rises and sets today
• Where the sun and moon are right now, corrected to true north
