Your whole day,
on one dial.
A 24-hour weather instrument for your wrist: temperature, rain and wind for the next day — not behind a tap, but always there, circling your watch face. Noon on top. Midnight at the bottom, where it belongs.
One glance. Twenty-four hours.
The temperature ring
Warmer hours reach deeper into the dial; the coldest hour of the night is a thin sliver. Day glows gold, night turns indigo, clouds fade it gray.
Rain, before it happens
A blue band grows outward wherever rain is coming — down to the minute where radar covers you. Snow turns it white; flash-flood downpours turn it warning red.
Wind mode
One tap flips the ring to wind and gusts, with compass directions around the dial. The band reads in Beaufort; storm-force winds turn it warning red.
Scrub through time
Turn the crown or tap the ring to move the marker to any moment in the next 24 hours and read that exact forecast.
Honest ambient
When your wrist drops, the face calms to the rain band and the time marker — glanceable, minute-accurate, battery-friendly.
Your location, blurred by design
Your position is rounded to about a kilometre on your device before any request leaves it — our server keeps only a coarse grid cell, never where you exactly are. No account, no ads, no tracking.
Screenshots Placeholder — real captures from the Pixel Watch go here.
