Seize the day.

You get of it in Silverton today. Sun keeps sunrise, sunset and the light you've got left on your home screen — worked out on your phone, from exactly where you stand.

Six ways to see it

See every look & theme →

The numbers are real.

Every time on screen comes from the same solar algorithm NOAA uses, computed on your phone — no network call, no account, no service that can go quiet. North of the Arctic Circle in December, Sun tells you the sun isn't rising today, instead of guessing. See the actual math →

An old clock, kept honest.

Three of the six faces draw on the Chinese five-phase and organ-clock traditions — sourced, not remembered, and shown as what the tradition holds, never dressed up as astronomy. Explore the dial →

Nothing to open twice.

No account, no notifications, no streak to keep alive. The sun doesn't rush and it doesn't need you to check in — it just keeps moving, all day, whether you're watching or not. Sun is built the same way: it sits on your home screen, quietly correct, and asks for nothing back.

One purchase, priced like one.

Sun has no server and no hosted data — nothing that costs more the longer you use it. So it's priced to be bought once, not rented.
