Cirrus on iPhone in dark mode on a clear night in Atlanta: 63 degrees and clear, high 77, low 57, the moon among the stars of a navy sky, nothing in the way of the stars tonight, and the Daily Cirrus card below: a low of 57 tonight and a high of 81 tomorrow.

Your morning in a minute

A sky that matches yours.

Cirrus paints its sky for the hour where you are. Fog and low clouds checked against the latest reports from nearby airports. Slide from sunrise to the stars.

Cirrus at midday in light mode, in Atlanta: the bright aqua sky, 75 degrees and a clear sky, high 77, low 58. About as good as it gets.

Cirrus at midday in dark mode, in Atlanta: navy into lagoon teal, 75 degrees and a clear sky.
Dark

Dark mode keeps each hour’s color, only deeper. After sunset the stars come out, with a faint Milky Way on clear nights.

Captured on October 6, mostly in Atlanta, with the sunrise from Honolulu and the morning from Seattle, each at that hour of its day.

Tap a question. Type your own in the app.

Active Storm

The warning tells you it’s coming.
Cirrus tells you what to expect.

When a tropical storm or hurricane is named, Cirrus pulls in the full picture: where it’s heading, how strong it’ll be, and when it could reach you. No advisories to decode.

  • The forecast cone and 5-day track, drawn from National Hurricane Center advisories
  • Category and wind speed, the numbers that matter
  • When the storm is expected to reach you
  • What to watch for: surge, flooding, tornadoes, and rip currents
  • Active warnings for your area, in plain words
The Active Storm detail in Cirrus: Hurricane Nolo, Category 1, winds of 85 miles per hour, moving past Lihue, not toward it. The map shows the forecast track and cone for the next 5 days west of the Hawaiian Islands, with Honolulu labeled, and how far the storm’s winds reach.
Hurricane Nolo, a real storm, 309 miles west of Lihue, Kauai. Captured September 30, 2026.

The Road Ahead

Don’t just check the forecast.
Check every mile of it.

Type where you’re going right in the card. Cirrus maps the weather mile by mile, with each city’s weather at the time you’ll get there and a warning if a storm is anywhere along the way. When you’re ready, hand off to Apple Maps, Google Maps, or Waze.

  • Your route colored by conditions: clear, rain, or storms, every mile
  • City‑by‑city weather at your actual arrival time
  • Severe weather warnings along your route, hurricanes and tropical storms included
  • Fog, smoke, or dust on the road gets a caution, never a “Clear to go”
  • Drive, Cycle, or Hike, with conditions matched to how you travel
The Road Ahead in Cirrus: a night drive from Amarillo to Albuquerque, arriving at 5:08 AM with rain possible. Under Severe weather on your route, a Flood Watch and a Flash Flood Warning near Amarillo. The route map is colored by the forecast, clear in blue and rain in purple.

Health

Your steps and your sleep, next to the weather.

With your permission, Cirrus reads your steps, sleep, and heart rate from Apple Health and sums them up in plain words, on your iPhone and your Apple Watch.

  • A sleep score from 0 to 100 for last night
  • Steps, sleep, and resting heart rate at a glance
  • A Sleep Coach you can ask about your night, in plain words
  • A short read on how you slept and how you’re moving today
