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!

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.
Rain you can plan around — and a watch rebuilt around it.
• HOW MUCH, NOT JUST HOW LIKELY. A 90% chance of 0.8 mm is a near-certain nothing; a 30% chance of 20 mm is the day worth moving plans for. Sky Warden now reads the two together and lets the ANSWER decide how loud a day looks. In the 7-day view only the days with real rain carry a stripe and a colour; the rest step back. The millimetres sit beside the chance at a size you don't have to lean in for.
• THE SCENE STOPS EXAGGERATING. Rain falling on the house now scales with the amount, not the chance — a drizzle is a drizzle and a trace draws nothing at all. The scene and the forecast beneath it finally agree.
• MORE HONEST RAINFALL. Sources that publish no volume were being counted as forecasting none, and observed rainfall — rain that had already fallen — was being averaged in as though it were a forecast. Both fixed. In inches, a trace reads as under a hundredth rather than a flat "0.00 in".
• APPLE WATCH, REBUILT AROUND THE VOLUME. The hour and week lists lead with the millimetres and a pill that makes a wet hour findable without reading every row. Twelve hours means twelve hours — the bar used to stop at midnight and shrink to a sliver by bedtime, hiding rain due overnight. Range ends, day letters and warnings are all legible at arm's length now.
• ONE DISCREET NOTICE ON THE WRIST. A small badge beside the location — red only for an emergency, amber for watch-and-act, slate for advice — opens Today: your warnings, the best window to be outside, source agreement, the rain total, UV and wind, plus the same alerts your phone is showing.
• TAP THE ARROW FOR WHERE YOU ARE. The watch can take its own fix and refetch for there, naming the place itself — so a watch that travelled without its phone stops reporting your weather under the wrong suburb.
• ELEVEN COMPLICATIONS, HONESTLY NAMED. "Rain chance" and "How much rain" are different questions and now say so. New: today's low and high at the ends of the arc; rainfall as the headline; and a split dial with temperature climbing the left and rain falling down the right. The temperature dial answers the only question people ask it — NAH, MEH or YUP — and it decides by expected millimetres, not by chance.
• THE HOUSE DRESSES FOR THE OCCASION. Near Halloween, a carved face glows in the window and a pumpkin sits by the steps. More through the year.
