User Reviews

Reviews consistently praise Xasteria as an easy-to-use, planning-focused astronomy weather tool with broad, multi-source data. The top positives are its planning utility and data coverage, which many users rely on to plan observing nights. Recurrent downsides center on UI readability and orientation: portrait-mode readability and a desire for better landscape support. A few users noted crashes or instability, but overall responses highlight strong value and ongoing developer responsiveness.

Pros

Easy to use and straightforward interface for astronomy weather planning.
Comprehensive weather data for planning observing sessions (moon/sun rise and set, clouds, seeing, etc.).
Strong planning tool that helps decide which nights to observe and allows easy forecast comparison.
Multi-source forecasts and data integration (including NOAA satellite data and Clear Outside).
Responsive development with useful updates and feature additions based on user feedback.

Cons

UI readability/accessibility issues in portrait mode and general orientation limitations; text/readout can be hard to read and not optimized for all users.
Lack of landscape optimization and landscape support; portrait-focused UI requiring rotation and sometimes two-handed use.

Recent reviews

Love the app. Latest 5.0 release doesn’t scale when viewed vertically on the iPhone. Annoying to rotate horizontally, sometimes requiring 2 hands. I miss the +/- buttons on previous version. The developers are amazingly responsive and have already contacted me for more info on my experience.

Cannot tell what the sky is doing because this app is too hard to see and read. Violates all visual accessibility requirements. Can’t believe developers are still trying to get away with apps that look like this.
