Comments on Mobile Observatory 2 - Astrono for Android

★★★★★ Matthew Westerfield · Apr 2, 2025

What a great deal for such an in-depth and informative app... I use it whenever there's a clear night sky. Thank you developer !!!

★★★★★ Peter P · Sep 23, 2020

I am new (again) to astronomy, looking for help, I found this app, and the reviews were good, so I bought it, thankfully I was not disappointed. I spend a lot more time exploring the app features, probably due to my lack of experience, but it is fun and interesting. I think its way undervalued, but then if it cost more I may not have tried it. HIGH recommendations from an old retired low tech guy! The more I use this app, the more I like it.

Best Astronomical App for all things like upcoming events like planets asteroids comets sun n moon solar and lunar eclipse planets position lots of stuff

Author forces users to buy new version by removing support for older devices (where it worked years without problems) even that they had already paid for older version.

Not sure why mobile observatory 2 wasn't just updated to mobile observatory 3 pro, so, in order to update from version 2 to 3 you literally have to buy a separate app? Wow!

Live view hasn't worked for the past 3‐4 years. It always switches to sky view whenever you move.
