Very good and important Works very well and fun to use.
Great work This app enables you to help conduct a survey of light pollution which is a major problem worldwide. It works quickly and easily and provides you with a star map for your efforts.
Auto Brightness Great except for one thing.Please fix the auto-brightness being disabled when using the app.
Great to be part of something Helps you understand how much we lose from light pollution.
Who doesn't want to "science"?! This app is a great way to learn about our night skies & help gather data for research.
