Every weather app sounds certain. None of them are.
They all read from the same handful of national models, pick one, round it off, and hand you a number with no error bars. When it turns out wrong you have no way of knowing whether it was a close call or a coin flip. Sunny goes one layer down, takes every one of them, and carries the disagreement out the other side — your location, right now.
Built on those: the seven services Sunny reads
This is the next 24 hours where you are.
Sunny reads seven forecast services, and underneath those sit the national models they're all built from — ECMWF, GFS, the UK Met Office, Japan's JMA. Here they are unaveraged, one faint line each. The bright line is the median across them, coloured by temperature along its length. This is your location, right now, not a mockup.
Right now they disagree by 4°F. Most apps would show you one of those numbers and never mention the others.
Your weather, in your hand.
Answers, not readings.
Three questions the app answers. Two are demonstrated on this page, live, for where you're standing — and the one that can't be says so on its face.
Can I run before the rain?
Set what counts as good weather for you — run in drizzle, but not in wind — and Sunny finds the windows in the next 36 hours.
Is it actually raining there?
Ask a place and get answers from people standing in it, kept visibly separate from the official layer. Never blended together.
Who is right, here?
Every night Sunny writes down what each source called for today. The next night it checks the call against a thermometer — the observed high at your nearest station — and takes the difference.
Half of weather is after dark.
The TONIGHT pane is one chart of the night — the moon riding its real altitude arc, ISS passes computed from live orbital elements, aurora reach, and the best window named plainly: DARK, MOONLESS & CLEAR. The feed finally gives your moon pics somewhere to live — kept visibly separate from the official layer, always. And the app counts the sky down on the Lock Screen: a tilde marks a nowcast estimate, and seconds appear only when orbital math has earned them.
Put it on a wall.
The week over full radar — no input, no login, made for the hallway TV and the shop window. It runs at a URL, which means the demo is not a video of it: the place rides in the address, so there is no account, no sign-in, and nothing to click Allow on. The address below already carries your place. It is live before you've decided anything.
sunnyweather.co/tv/dphgr6Open the wall →Twenty-five characters, every one on a TV keyboard's first page — the last six are the place. No account, no app, nothing to pair. Add ?trim=7 if your TV crops the edges.
One plan. Everything included.
The forecast, with the doubt left in.
Ten models, seven services, every place they disagree — and a nightly ledger of who was right. Everything included, free at launch.
