A clear sky.
The whole story.
Fewer clouds do not always mean a darker night. Discover what makes the difference.
Cloud cover
Room between the clouds.
Even a thin, high veil can change your view. See total cloud cover and the low, middle and high cloud layers by the hour.
Moonlight
The moon joins in.
Beautiful to observe, bright beside faint nebulae. See when the moon rises and sets, how high it is and how much of its disc is illuminated.
Darkness
Wait for the real dark.
Sunset is not the start of night. The app calculates astronomical darkness and explains why summer nights sometimes never get completely dark.
Not every night is clear.But you will want tocatch the one that is.
Pro lets you know when the forecast for your place is good enough. Find a clear spot nearby and see how the weather models agree about the night.
ProA view of the sky. Grounded in weather data.
The forecast uses DWD ICON-D2, ICON-EU and ECMWF IFS. Moon and darkness are calculated for your place. The further ahead you look, the greater the uncertainty.

So is the anticipation.

Before you head outside.
Can I download the app yet?
Starclear is being prepared for iPhone and Android. As soon as the app is publicly available, you will find direct links to both stores here.
Where does the forecast work?
The app is designed for the Netherlands, Belgium, Luxembourg, Germany, Austria, Switzerland, Liechtenstein, Denmark, Czechia and Slovenia. Available weather models vary by location.
Do I need an account?
No. Choose a place and see the forecast without an account. Apple or Google handles an optional Pro subscription.
What counts as a clear night?
By default, the app looks for at most 20% cloud cover for at least three consecutive dark hours. If darkness is shorter, it never asks for more clear time than that period. Bright moonlight is mentioned separately.
Does this guarantee good stargazing weather?
It is still a weather forecast. Clouds may turn out differently, and the app does not predict seeing, transparency or light pollution. Check the conditions yourself before you set off.
How do I manage my subscription?
Subscribe to Pro in the app. Manage, cancel and request refunds through the App Store or Google Play. You can restore an existing purchase in the app.
