User Reviews

Mobile Observatory Astronomy is praised for its rich and comprehensive astronomy data, realistic night sky visuals, and user-friendly features catering to amateurs and enthusiasts alike. Users appreciate its detailed celestial object database and event planning tools. However, multiple reviews mention problems with star glare, sky chart drift, and VR mode difficulties. Some catalogs are incomplete for advanced querying, and the night vision mode is criticized for being too dark. Occasional issues with notifications and ISS tracking were also noted, but the developer is responsive and updates the app regularly.

Extensive and comprehensive astronomy information suitable for beginners to amateur astronomers.
Realistic and detailed night sky graphics and live views, including features like AR and celestial events planning.
High-quality and large database of celestial objects, updated regularly.
Good user interface with many useful features like location saving, event notifications, and smooth animations.
Responsive developer and regular updates to improve the app.

Cons

Issues with star glare and flare effects that can make the sky view unusable for some users.
Drift and stuttering in sky chart movement and VR mode, affecting user experience.
Some incompleteness and gaps in astronomical catalogs, affecting intermediate and advanced users.
Night vision mode is too dark and red for some users, limiting usability in low-light conditions.

Recent reviews

Unusable. In order to show the sky "realistically" many of the brightest object will flair / glare / etc the view out, making it unusable. You can control the glare / flair of the sun and the moon but not the stars. I have checked every single "settings" menu / setting. no go. I want it to look like the screenshots on this listing! Some features are still good.

Best observatory app ever. Like having an encyclopedia for the cosmos in your pocket. Wish it was a little less touchy with the locking and unlocking every time, but I probably just don't fully understand how to use it or I need to just get used to it. Not a problem really. I am having issues running the app right now but it seems like the issue is on my phone. Already updated, uninstalled, reinstalled, about to uninstall and restart my phone then reinstall again. We'll see what happens :{|l!'`
