What's New in NightFall
3.0.1
September 25, 2026
* Switch the star chart between your destination and your starting point to compare the same night at both places. * Deep-sky objects now cover all 109 Messier objects, each with its real magnitude, and constellation lines are drawn only for the one you are looking at. * Cleaner mountains: no more banding while you pan, and the air's own glow now covers the ground near the horizon instead of leaving a black edge. * Added Japanese and iPad landscape.

FAQ
What is NightFall?
NightFall is an application designed to help users find the darkest skies for stargazing. It provides a light pollution map, detailed star charts, and planning tools for optimal viewing experiences.
How does NightFall help me find dark skies?
NightFall displays a map color-coded to show nine levels of light pollution. Warmer colors indicate brighter skies, while cooler colors signify darker, more suitable conditions for stargazing.
Can I use NightFall offline?
Yes, NightFall offers full offline functionality. The star catalog, Milky Way data, and terrain information are all available within the app, making it usable even without a signal.
What information does NightFall provide about a stargazing spot?
When you tap on a location, NightFall shows its visibility level, elevation, coordinates, and estimated drive time and distance from your starting point. You can also view details like zenith brightness.
Does NightFall have ads?
No, NightFall does not contain advertisements. As a paid application, it offers an uninterrupted user experience focused on stargazing.
What devices is NightFall compatible with?
NightFall is a universal app, meaning it is designed to work seamlessly on both iPhone and iPad devices.
How accurate is the light pollution data in NightFall?
The light pollution map is based on NOAA VIIRS night lights and the Light Pollution Atlas, providing an estimate of zenith brightness. However, it's a model and doesn't account for horizon glow, so real skies may appear darker than the map suggests.
What is the price of NightFall?
NightFall is available for a one-time purchase of $1.99. This grants you full access to all its features without any subscriptions or in-app purchases.
