Most weather apps pick one model and hide the rest. Sky Warden reads many of the
world's leading forecast models at once — ECMWF, GFS, ICON, UKMO, GEM, Apple
Weather and more — and reconciles them into one honest read: the temperature,
the rain, the wind, HOW SURE the models are, and where they disagree.
When every model agrees, you get a confident answer. When they split, Sky Warden
shows you — the exact number each source gives, and how far apart they are — so a
"90% chance of rain" you can trust never looks the same as a coin-toss.
A LIVING FORECAST
• A hand-drawn scene that redraws with the real conditions — sun, cloud, rain,
wind, waves, the moon's phase, day into night — for your exact place.
• Three home views: a picture-first Scene, a plain-language Simpler read, and a
Details dial that shows every metric and the consensus confidence at a glance.
HONEST BY DESIGN
• A confidence reading on every forecast, from the models' actual agreement.
• Tap it to see where the sources differ — each model's value, side by side.
• Your own corrections ("it says rain, it's dry") are respected.
HOUR BY HOUR, FOR WHAT YOU ACTUALLY DO
• Temperature, rain, wind, UV and humidity — each with its own hour-by-hour view.
• Rain has a "hide dry hours" toggle, so you see WHEN it rains, not a wall of 0%.
• Tides and a full marine read (waves, period, sea temperature).
• Live rain radar with a play-through timeline.
MORE THAN A FORECAST
• Solar & energy: when the sun's strong enough to run the dishwasher or charge —
and, in supported regions, how clean the grid is right now.
• Plans: reads your calendar and flags weather that threatens outdoor events.
• Sky: meteor showers, eclipses, moon phases and space-weather news.
• Rain-approaching notifications before you get caught out.
PRIVATE
No account, ever. Your location is used only to fetch the weather
and is never tied to your identity. Your calendar is read on your device to flag
events — it never leaves it. Two small, non-personalised ads keep Sky Warden free.
Sky Warden is for anyone who's been burned by a confident forecast that was wrong —
and would rather know when the models can't agree.
Sky Warden is easily the best weather app I’ve used. Instead of relying on a single guess, it compares major global models (ECMWF, GFS, ICON) side-by-side so you can see the actual forecast confidence at a glance.The visuals are informative, the interface is clean and clutter-free, and there is a one-time purchase to remove ads for a very reasonable price. Beautifully designed and genuinely dependable. Additionally, the developer is quick to respond and provides updates and fixes based on user feedback. A+ experience.
Suddenly has ads!
sharkamonkey
Don’t update. Didn’t have ads before and now it does. If a change is needed to make income I understand adding ads but, it shouldn’t affect those already grandfathered in. Also nothing in the update notes saying that ads were being added. Was loving this but, will be going back to my old weather app.
A big global update.
• Aurora forecast, in the Sky tab — an honest, location-aware read on whether the northern or southern lights are on the cards tonight, from live NOAA space-weather (and whether your sky even gets dark enough to see them).
• King tides — know when the year's highest tides are coming, with the water brought to life right in the scene.
• Worldwide hazard warnings — tropical cyclones, floods, earthquakes, volcanoes and wildfires anywhere on Earth, with a cyclone's forecast track and closest approach to you, plus a global flood outlook. Tap any warning for the detail — a live cyclone track map, or the river-discharge chart behind a flood.
• Smarter activities — a cyclone, flood or king tide now shapes what's a good idea today.
Plus refinements and fixes throughout.
