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.
