User comment: Fantastic! Settling the argument with my observing friends over which of our sites is better is worth the $5 all by itself. And if I win the wager for a beer, it will be like getting the app for free.

DSM supports the Globe at Night campaign by delivering data

👤 🕔 February 4, 2014 Comments Off on DSM supports the Globe at Night campaign by delivering data

We work together with the worldwide Globe at Night campaign. The app will deliver your submissions to the researchers at Globe at Night. Note that no personal data is submitted and locations are rounded by 2 decimals (this means that your location is not exactly shown or transmitted, only approximate (50-100m))

Android and Windows phone not supported, here’s why.

👤 🕔 January 7, 2014 11

Don’t get us wrong. We love the Android platform. But it has a drawback: there are too many different devices with different camera models. That makes it practically impossible to create a reliable dark sky meter.

Android users can use the Loss of the Night app to measure light pollution (using naked eye estimates)

Discontinuing Dark Sky Meter Lite and price Pro product

👤 🕔 October 4, 2013 Comments Off on Discontinuing Dark Sky Meter Lite and price Pro product

 

We are planning to discontinue the Dark Sky Meter Lite product this year. The Dark Sky Meter pro sales do not cover the hosting costs of our back end provider and the lite product generates a lot of extra traffic (we pay for that in our back-end system). The lite users can continue to use their product.

We also will raise the price of the Dark Sky Meter product a little bit to cover the hosting costs. We eventually will put the lite product back in the store for special occasions (like the Globe at Night campaign).

 

iPhone 5C, 5S Support, Map updates – on the site , Globe at Night, and more

👤 🕔 October 1, 2013 Comments Off on iPhone 5C, 5S Support, Map updates – on the site , Globe at Night, and more

The iPhone 5C has the same sensor as the 5. We will provide a quick update soon, also covering some iOS7 issues like white backgrounds and more.

The 5S has a different camera, as soon as we get hold of this device, and do some testing the app will support the 5S too.

The map on this website is updated frequently (by hand) , the reason is both technical as logical: i always filter out nasty readings (for example SQM>23) and incomplete readings (for example those without location). After that i refresh the database that’s providing the map data.The map shown in your app is always ‘live’.

IDA’s Scott Kardel will hold a talk about our app at the ALAN conference. We are very thankful for that!

The app will provide data to the Globe at Night campaign in 2014. We are very happy to support them.

 

Sep 2013: over 2000 validated measurements!

👤 🕔 September 10, 2013 Comments Off on Sep 2013: over 2000 validated measurements!

As the nights become longer in the Northern Hemisphere, the amount of measurements is increasing. Resulting in a great map of sky brightness. Team member Joep has updated the map and grouped the results diflucan tablets buy online.

For now, the map is updated by hand. We scan for bad measurements (eg 22 or higher, or without location). After validation we update the map. Note that in the pro version, the app is really live and you can manage the measurements in the ‘my data’ tab.

 

Dark Sky Meter a big success!

👤 🕔 May 7, 2013 Comments Off on Dark Sky Meter a big success!

A lot of websites, social media,  internet forums and the official press release from the IDA triggered a lot of downloads and qualitative data. Thanks for that! Expect a Google map with all the valid readings on our site soon.

What’s in the submitted data?

👤 🕔 April 20, 2013 Comments Off on What’s in the submitted data?

This is a snapshot of the data collected. You can see that no personal data is involved. Your GPS location is randomly rounded to 800 Meters, so people will not get in your backyard when measuring diflucan tablets. We collect the moon phase, device angle and cloudyness. And of course the software version. (We assume that pro users are somewhat more experienced).

Remember: submitting will deliver data to non profit awareness programs and universities. There are no commercial purposes. And of course you don’t have to submit the data!

Dark Sky Meter and Dark Sky Meter Lite released!

👤 🕔 April 19, 2013 Comments Off on Dark Sky Meter and Dark Sky Meter Lite released!

Finally! Apple has approved the dark sky meter after a long wait. Both lite and pro apps are on the app store now! The Dark Sky Meter is an affordable app to measure light pollution.

App differences
Lite version only shows the number of times the sky is bright as a natural clear sky
Pro version outputs SQM (18–22), has a light pollution map and a cloud forecast.

Link to the Lite app (free):
https://itunes.apple.com/app/dark-sky-meter-lite/id626796278?l=en&mt=8

Link to the Pro app ($4.99 )

If you have questions, or would like to recieve a promo code for a review, please let us know.

An important note:
Apple forced us to support the iPhone 4. Because it has a camera which is very bad at low light conditions, every measurement at or above SQM 20 is unreliable.
Thanks for reading and enjoy the app!
