10 days, with honest confidence

Every day is marked high, medium or low confidence, from the spread of the forecast or how far ahead it is. Never a made-up percentage — and you always see when the forecast was updated.

Forecast scenarios agree closely: steady rain from early morning, easing to showers by evening.

Dot under each day: high, medium or low confidence.

Open it. The answer is at the top.

No tutorial, no sign-in, no permission asked on first launch.

  1. Pick a place

    Search for any city in 21 languages, or tap "Use my approximate location". Save up to 20 and reorder them.

  2. Read the day

    The weather now, a sky drawn from the real weather with the sun on its arc, and the day in one sentence.

  3. Look ahead

    The next 12 hours of rain, 48 hours on one ribbon and 10 days with their confidence — in the Nordic countries, rain every 5 minutes.

  4. Keep it on your home screen

    Five widgets refresh on their own, and if their data is more than 3 hours old they show its time instead of pretending it's new.

Private by design: what leaves your phone

1B Weather talks only to our own forecast server — and it gets as little as possible.

  • No ads, no analytics, no crash reporters and no third-party SDKs that use the network.
  • Coordinates leave the phone rounded to a cell of about 2 km: the server never sees where you are exactly.
  • The server keeps no logs per request or per user — not your IP address, not your places, not your searches.
  • MET Norway gets the forecast request from our server, never from you: it never sees your IP address.
  • Approximate location is optional and asked for only when you tap it — never precise, never in the background.
  • No account and nothing to sign in to. Your places and settings stay on your phone.

Everything you look at, nothing you don't need

  • The sky right now

    Temperature, feels like and conditions over a sky drawn from the real weather, with the sun on its real arc. Never a photo.

  • The day in one sentence

    "Rain from 5 PM, take an umbrella": a short summary of the day at the top, before any number.

  • 48 hours on one ribbon

    Temperature, rain and wind together, with the band coloured by temperature. Plus the next 12 hours of rain at a glance.

  • 10 days, honest confidence

    High and low, rain in mm and chance, wind and a detail card for each day, marked high, medium or low confidence.

  • Widgets that don't go stale

    Five sizes, a city for each, transparency and theme. They refresh about every hour, on unlock and when the connection comes back.

  • Your places

    Up to 20 cities, reordered as you like, with the local time next to each one. Approximate location only if you want it.

  • Morning summary

    An optional daily notification at the time you choose, with the day's summary for your first place.

  • Phone, foldable and tablet

    Unfolded or on a tablet, your places on one side and the forecast on the other. Light and dark theme, TalkBack with full sentences.

Where the data comes from

Sunrise, sunset and hours of daylight are calculated on your phone.

Good to know

  • 1B Weather is not an official warning service: it does not show official severe weather alerts yet. For safety decisions, follow your national weather service.
  • Rain every 5 minutes for the next 90 minutes is available only in the Nordic countries; elsewhere you get the next 12 hours of rain.
  • An Internet connection is needed to update the forecast; without one, the app and the widgets show the last saved forecast with its time.

Privacy at a glance

  • No ads, no analytics, no account and no third-party SDKs that use the network.
  • The app only talks to our own forecast server. Places leave your phone rounded to an area of about 2 km, never your exact position, and the server keeps no records per user.
  • Approximate location is optional, asked for only when you tap it, and never used in the background.
