Comments on Mobile Obs Pro Astronomy for Android

★★★★★ Billy Blazes · Aug 25, 2025

This is the first app that I actually paid $$$ for, and it is worth every penny. Gives so much information for sky watching. Love it!

★★★★★ Nevenincs · May 2, 2025

Probably the best astronomy app out there, but it has not received any version updates since 2023, and the developer is not giving any information about what to expect (or not). Still 5 stars, though.

★★★★★ Roy Alexander · Apr 6, 2025

Brilliant all round astro app and widgets - from an observatory director and astronomer

★★☆☆☆ Geir Laastad · Nov 6, 2025

Latest PRO version update is a BIG DOWNGRADE. Why editable location features and icon reorganization is removed is beyond me. The app was better before, much better.

★☆☆☆☆ Comander AGC · Sep 16, 2025

This app appeared, at first, to be informative, easy to use, and educational. That was until I started to look more closely at a certain comet (C/2014 UN271). Initially, the app showed the comets' path would take it to within .02au of earth in Feb2031 which contradicted the astronomers who said, "it would be a billion miles away at around the orbit of Saturn." before heading back out of the solar system. Now, the owners have erased all the data relating to the comet from the app. Curious!

★★☆☆☆ Charles Cotton · Dec 14, 2024

Unusable. In order to show the sky "realistically" many of the brightest object will fair / 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.

★☆☆☆☆ Ali Fugu · Nov 20, 2024

The updated app is giving live view of sky as and due.
