不建议购买
有点坑。 还不如直接查数据，功能比较鸡肋，而且不完善

不错的应用，一下把几个应用功能集齐了
不知道为什么推荐目标的具体信息一直加载不出来；要是星空支持直接用手点星看其具体信息就更好了

What's New in NightFall
3.0.2
October 11, 2026
- Pick a spot — from search, a saved place, or a station — and it stays pinned on the map: panning around just looks elsewhere while the card keeps describing it (visibility, elevation, drive time, saved state). Before, a small drag dropped it and you had to search again. - While something is pinned, the crosshair steps aside and a ring marks the spot. Tap “Back to map center” at the top of the card (or tap empty map) to pick with the crosshair again. - Places found through map search can now be pinned and show their name, too.

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.
