Know tonight’s sky before you go.

Yes. Free, with no ads and no tracking. It’s coming soon to the App Store in the United States, for iPhone with iOS 18 or later.

It reads the hourly forecast at the minute the colour peaks, a couple of degrees of sun below the horizon. It looks at the cloud overhead and how high it sits, the cloud along the light’s path in from beyond the horizon, haze, humidity, rain, and whether a storm is clearing. Then it gives one number from 0 to 100 and says what it saw. It never guesses past the forecast.

Same model, checked against the same set of skies so the two can’t drift apart. What differs is the weather they read. The app works it out on your phone for exactly where you stand, using Apple’s cloud forecast, which says how high the cloud sits. This page reads the cloud layers from Open-Meteo for the place you pick, rounded to a few kilometres. Most evenings the two land close. When they don’t, trust the app: it can see the cloud’s height, and this page can’t.

The times and the Sky Score here work anywhere in the world. The app is coming to the US App Store, and its checked places are in the United States for now.

We research them ourselves, from maps, satellite pictures and the official park, city or land pages for the ground they sit on. Then a person checks the pin against the map, checks the place is open to the public, and approves it one fact at a time before it goes in, here and in the app. That work happens at a desk, not on the ground, and nobody from Skysta drives out to a spot. Anything that looks closed, private or too hard to get to is turned down. You can suggest one too, and a person reads every one.

“Show on the map” starts off, unless you choose otherwise in Settings, and one tap decides each photo. Leave it off and the map shows your town at most, never where you stood. Turn it on and a pin drops exactly where you stood.

There are no ad libraries and no third-party trackers, which is why the app never asks for the tracking permission. Diagnostics are off the day you install it and stay off until you switch them on. No public likes, no followers, no streaks, and nobody can see how many skies you’ve shot. You share one sky each time the camera opens.

No. No cookies, no analytics, no third-party scripts. The cities’ times are worked out in your browser, and it reads where you are only when you press a button. When you check a sky, the place goes to our server and on to Apple Weather and Open-Meteo for the forecast. Our server writes nothing down and holds answers in memory for up to a day, though Google’s request logs for that server can hold it for up to 30 days, and we don’t use them. If you share where you are, your position is rounded to a few kilometres before it leaves your browser, and that rounded place is what goes to OpenStreetMap to find the name of the town. A link you copy to a sky holds the place you looked at, rounded the same way, and nothing about you. The whole list is in the privacy policy.
