New press release put out today about an Android app to measure light pollution with a star counting method & will be able to be integrated with GLOBE at Night:

There's also a new iPhone app that works like an SQM. More info is here:

http://www.darkskymeter.com/

I have tested the iPhone app and it works very well on my iPhone 4S. The "Lite" free version tells you how many times brighter your sky is over a natural one and the "Pro" version ($3.99) gives measurements in mags per square arc second. It compares very favorably to the SQM.

I also bought the Dark Sky Meter app for my 4S as I wanted to support this initiative. The price is really fair compared to the SQM meter. Both the freeware and the Pro version enable the user to upload their measurements (and both versions will send the same kind of SQM info to the webserver). If I understood well, the writers of the app will share these measurements with IDA and other Dark Sky associations so there will be more objective light pollution information available over time.

I would say: give it a shot too when you have an iPhone 4S or 5 and help updating the LP database. If you don't want to pay for it, then just download the freeware version.

See this thread in the computer and software forum for more info:

I've tried and compared the full $5 app to an SQM meter with good results on my 4S iPhone.

I just got it, now I have to figure out how to use it? Anyone have a link to understand how to read and interpret SQM numbers?

Thanks,

Bob

Bob, Unihedron has an FAQ that might be of use to you:

For those that can't get the Dark Sky Meter app in different countries, hang on, I will ask the developer about that.

I asked the developer of Dark Sky Meter about its availability worldwide and here is what he had to say:

"The app is available worldwide. The reason the can't buy it is because they have an unsupported model (eg: 3GS, iPad, iPod). Apple is a little confusing sometimes."

I hope that helps.
