Why your weather app gets sunsets wrong
A sunset is not weather above your head. It's an optics problem spanning hundreds of kilometres — and that's what we compute.
1
The color comes from far away
At sunset, light grazes the lower atmosphere for hundreds of kilometres before it reaches the clouds above you. A clear slot on the horizon 200 km away — not the sky overhead — is what turns cloud undersides red.
2
We sample the whole corridor
Layered cloud, cloud base, humidity and aerosols at eleven points along the sun line — curvature-aware, so a distant cloud only counts if the light ray actually passes through it.
3
You get a verdict, not homework
A 0–5 score, GO / MAYBE / SKIP, the reasons in plain words, and the golden-hour outlook. The full sky cross-section is right there when you want to argue with it.
Plus a forecast if special conditions might occur
The same corridor data watches for the fleeting conditions photographers actually chase — telling you when to look and which way to face, never a “drive here”.

No black box
Forecasting sunsets honestly means showing the uncertainty, not hiding it.
Every forecast explains itself
Main reason, supporting factors, and risks — in sentences, not symbols. If we say SKIP, you'll know exactly which clouds are to blame.
Two forecasts compared
We compare two forecasts for the same sunset or sunrise. If their ratings differ, we show both.
Versioned and accountable
Every prediction is stored with the exact model version and data sources that produced it. When we improve the model, past forecasts stay attributable.
Calibrated by real evenings
The morning after, one tap tells us whether it was worth going out. Your ratings are the ground truth the model is measured against.
App made for landscape photography

Fair questions
How accurate is it?
+
A sunset forecast is a probability, not a promise. We compare it with a second forecast when available and show when their ratings differ. We also store the scoring version behind every prediction and measure forecasts against real outcomes.
It's overcast at my house — why would the app say GO?
+
Because the color doesn't come from above you. At sunset, light travels hundreds of kilometres through the lower atmosphere before it reaches the clouds over your head. Overcast overhead with a clear slot on the horizon 200 km away often means the underside of that overcast turns red — the best sunsets frequently look hopeless until minutes before. The reverse also holds: a clear sky above you with a wall of cloud on the horizon gives nothing.
What data does it use?
+
Commercial Open-Meteo forecast data. Every run samples layered and pressure-level cloud cover along the light corridor out to 350 km, plus cloud base, humidity, precipitation and aerosol optical depth. A second forecast is used for comparison when available; if their ratings differ, we show both.
Can I install it on Android?
+
Yes — SunsetVue installs to your home screen like any app, with no app store and nothing to download. Open sunsetvue.app in Chrome, tap the browser menu, and choose “Add to home screen” (some phones call it “Install app”). It then opens full-screen from your home screen, which is the point: the plan has no alerts, so the icon is the reminder.
How do I install it on iPhone?
+
Open sunsetvue.app in Safari, tap the Share button at the bottom of the screen, scroll down and choose “Add to Home Screen”. It then opens full-screen from your home screen, which is the point: the plan has no alerts, so the icon is the reminder.
If you opened this from an email or another app, you are in that app’s built-in browser and the option will not appear. Tap the … or Share menu, choose “Open in Safari” first.
Is my sunset spot safe to reach?
+
That's yours to judge — and we say so plainly. SunsetVue forecasts light, not trail conditions, avalanche risk, or road access. Check official sources like MeteoSwiss and the SLF bulletin before heading into terrain.
Can I try it before paying?
+
Yes. Choose a location and explore the rest of today and all of tomorrow, free — Overview, Sunrise, Daytime, Sunset and Night, with real forecasts. Your results and that location are saved. After it, a 14-day free trial starts when you decide to continue, and nothing is charged until it ends. Everything you saved stays yours either way.
Why do you ask for a card before the trial?
+
Because the alternative is asking you to decide twice — once now and once in two weeks, when the novelty has worn off. The card is not charged during the 14-day trial. We email you before the first charge, you can cancel in two clicks from the billing portal, and cancelling during the trial charges nothing at all.
Can I cancel the paid plan?
+
Anytime, in two clicks, from the billing portal. You keep access until the end of the period you have already paid for. After that forecasts stop, but nothing you saved is deleted — your spots and history are waiting if you come back. The 14-day trial does not charge until it ends, and we send a reminder before it does.
