Dark Sky Meter


Open iTunes to buy and download apps.


As seen on BBC, CBS, Scientific American and more!
The Dark Sky Meter measures the artificial sky brightness in two simple steps. Just cover the camera and aim to the point right above your head. The output is the same as a commercial Sky Quality Meter...
But at a fraction of the price! The app can submit your measurements to the International Dark Sky Association.
This app works fine on iPhone 4S or higher.

Attention: if the app crashes at startup: please give the camera access to the app! It can be done using settings-->privacy--> camera.

But there is more:
- Real Time Map view: view your recent dark Sky Measurements and those of others nearby or world wide!
- Cloud prediction clock. Shows cloudyness for the next 4 days.

The app was tested world wide and is supported by the International Dark Sky Association.

What's New in Version 2.1.2

Shows a message when camera is turned off due to privacy setting.
Small improvements.
As i cannot respond to user reviews containing bug reports, please send bug reports to, so i can help.

Customer Reviews

Works great on iPhone5s (not on 6 though)

I've had good results with this on my iPhone5s. The results seem relatively reliable and consistent with dedicated SQM meters. Definitely well worth the price!

However, many members of my astronomy club have tried this on their iPhone6/6 Plus and are finding the results are very inconsistent and completely useless.

Not Usable

This app only seems to have a hand full of people uploading in my state. It doesn't seem to show much of anything. I see a few uploads but not in the spectrum of colors shown in the legend. Darkskyfinder website is much much better and free.

So cool

This app helps you measure the night sky brightness with a press of a button.
