"Contribute to a world-wide citizen science project." (The Guardian)
"Find out exactly how bad the light pollution is." (Chandra Clarke, citizensciencecenter.com)
"The app couldn't be easier to use, and you can even learn different constellations along the way." (Nicholas Fordes, plos.org)

The Loss of the Night app turns your eyes into a light meter, allowing you to become a citizen scientist and report how bright the night sky is where you live!

In many parts of the world, the night sky shines with wasted artificial light from poorly designed street lamps. Skyglow outshines the stars in the skies, and dramatically changes the natural nighttime environment. Scientists are concerned that light pollution might have a big impact on nocturnal ecosystems, but they have very little information about how bright the actually sky is worldwide, or how skyglow is changing over the years.

You can help monitor skyglow using this app! It's based on Google's Sky Map, and lets you make measurements with a very sensitive, stable, and well understood light meter: your eyes! All you need to do is look for certain stars in the sky, and tell us whether you can see them or not. Using the Loss of the Night app is both fun and educational, and it also generates important scientific information that might help to protect the environment in the future.

After you've finished your measurement, your data will be anonymously sent to the GLOBE at Night project. You can see it on a map, check how accurate your measurment was, track changes over time, and compare it to other observations from around the world at http://www.myskyatnight.com.

Counting stars is a great experience and family activity, and you might find that you learn the names of stars and constellations without even trying. Students can use the app to measure skyglow and star visibility for their own science projects, and at the same time be part of a global citizen science network. The most important information for this project comes from brightly lit places where you can't see many stars, but you're welcome to use it in places where you can still see the Milky Way. If you’re lucky enough to be in such a place, let others know!

Satellites look at the ground, not the sky. By comparing the skyglow to the ground brightness, you will help communities learn what types of lamps light the streets instead of the sky. Hopefully in the future, cities will save energy and money, while having appropriately lit streets, dark bedrooms, and a sky once again full of stars.

Lots more information, including details of preliminary results, is available on the project blog: http://lossofthenight.blogspot.com and the campaign website of seeing stars Leiden: https://seeingstarsleiden.pocket.science/

You are welcome to get into contact with the light pollution researchers from Verlust der Nacht that built this app, and learn about their other projects (https://www.verlustdernacht.de). The app also provides some basic information on the history, importance, and consequences of artificial light at night.

This project was sponsored by the Federal Ministry of Education and Research (Germany).

    No longer works correctly on Android 11, and I had trouble with it on 10 as well. It's been something like five years since an update.

    it's phone friendly, accurate, and extremely helpful to the creators for Loss of the night. I'm so glad I installed this a long time ago. it's night mode makes it very easy to use without having to let your eyes readjust every time you need to find another star. thanks!! glad I could help in the name of science and astronomy!

    Now that I've used the app a while, I find a great value in its usefulness and design. It does need a way to edit reports. I'd also like to see a way to make reports without internet access such as in remote locations.

    Great app! I'm fortunate where I live to have relatively low light pollution, so many stars about magnitude -5 are visible to my eyes. Helps that I also an an amateur astronomer.

    Great idea, but app is defective in Northern CA, USA. Feedback selection directs to send an email, but gives no recipient address.

    I have enjoyed using on my LG phone. Recently I noticed that my observations have not been uploading. But I am glad this app exists!

    This app is so easy to use and educational. It also enables the average person to collect real data to help scientists curb light pollution!! Highly recommend!

    App is being used to target areas with "light pollution" that reside in areas close in proximity to overwhelming and substantial "light pollution" (e.g., Casinos, Heavy Commercial, Major Interstates, etc.) that tend to elevate surrounding levels of crime...that naturally just elevates surrounding light levels as due diligence. I don't appreciate crusaders that want to tag houses with motion sensor lighting. It's at best misguided, at worst, used by criminals. I have motion lights or 9mm rounds?

    Great app. I have a question though. My measurements transmission status is waiting for a week. Is this an issue?
