Light Pollution Map is an app that helps users locate dark sites where the sky will not be affected by light pollution. This feature allows for the best observance, star gazing, and photography of the night sky. The app also includes an integrated light pollution map that helps users find the darkest places near them. It also has the ability to save and load favorite dark sky locations, fully adjust the light pollution map overlay opacity and map type, and a unique "horizon safe radius tool" to avoid light pollution on the distant horizon.

In addition to the light pollution map, the app also has an integrated cloud cover map and temperature indicator. This feature allows users to know before they step outside if it's worth going outside to see the night sky. The app also has an Aurora overlay that allows users to see where the best viewing of the Northern Lights (Aurora Borealis) currently is.

The app also includes an ISS Tracker that allows users to follow the international space station on a live map. Users can see when it's flying above their location, who is currently on the ISS, view a live ISS webcam, and more. The app also has alerts and notifications that can be configured to send alerts for the next meteor shower, super moon, or lunar eclipse. The app can also alert users when aurora activity is high and viewing is good at their current location, and alert them when the international space station will be flying above them.

Overall, Light Pollution Map is a comprehensive app that offers a variety of features and tools for the hardcore astronomer. It is the only app users need to master the night. Some features are not available in the free version and may require an additional in-app purchase. The app offers several upgrade packs, or a monthly subscription with a free trial.

Light Pollution Map also includes live aurora and magnetic field information, astronomy calculators, live aurora webcams, a moon position tool, a night sky calendar, live NASA SOHO images, astronomy photo of the day, widgets, and night mode and AMOLED themes.
