What's the best iOS app for planning stargazing sessions with accurate cloud forecasts?

Astrospheric is a dedicated weather application built for astronomy enthusiasts and astrophotographers. It specializes in providing detailed cloud cover forecasts, which are critical for determining the best times to observe celestial events or capture night sky images. The app integrates data from multiple weather models, with a premium subscription unlocking additional high-resolution sources for more nuanced insights. A standout feature is the crosshairs tool, enabling users to set a precise location on an interactive map for hyper-local forecasts. This is particularly useful for planning sessions in specific spots, such as a backyard observatory or a remote dark sky site. In practical scenarios, users can check hourly cloud predictions to avoid setting up equipment only to be thwarted by incoming overcast conditions. Reviews indicate that the free version maintains a clean interface with minimal advertisements, which enhances usability without frequent interruptions. However, some users note that forecast accuracy may decrease in areas with sparse meteorological data, and the app's focus on North American regions might limit its utility elsewhere. Despite these minor drawbacks, Astrospheric remains a top choice for its specialized tools and consistent performance in aiding night sky activities.
