User Reviews

Mobile Observatory 2 is praised for its rich astronomy content, ease of use, and useful features tailored for both enthusiasts and casual users. However, multiple users report issues with the app's directional accuracy during live view, and many express frustration over upgrade costs and unclear policies. New users may find the interface complex and overwhelming. Additionally, support responsiveness is a concern. Overall, the app remains a valuable tool for astronomy lovers, despite these recurring drawbacks.

User-friendly and provides relevant features such as 'Tonight's Best' for local observations.
Highly valued by both amateur and casual astronomers for tracking and learning about celestial events.

Cons

Directional accuracy in live view is often off by a significant margin, making sky orientation unreliable.
Updates and upgrade policies are seen as expensive and confusing, with users frustrated about paying again for what was expected to be included.
User interface can be crowded and overwhelming for new users, with some preferring simpler or more intuitive apps.
Customer support is lacking, with unresponsive developers and insufficient documentation for upgrading or troubleshooting.
Some users find the educational-style graphics and interface waste screen space and prefer a more streamlined design.

It is dead, Jim. Despite the promise of "maintenance", catalogs are not available anymore. What if we, the v3 users need this for older devices, on which the hog that is v3 doesn't even work? So nice to hang us to dry...
