A must-have for amateur and professional astronomers alike. This app is well-designed, making it easy to get to whatever data source you require, such as knowing when is the best time to view the moon or planets. Tons of knowledge is available in just a few clicks, something I greatly appreciate. Highly recommended!

It's the only astronomy app I use on an almost daily basis and has served me very well over the years.This new version has some nice new features, but the biggest and best improvement for me is the graphic depiction of the night sky - especially during twilight. If I had to choose just one app to recommend someone - paid or free - I would recommend MO.

Great app, almost overwhelming in scope. However thanks to this app, I had no trouble finding the currently very visible comet C/2020 F3 (NEOWISE) and it also told me what the best time was at my location to look for it. This was awesome!

I have a library of astronomy apps. Each does a few things well but I was always looking for something that did more. This is the one. The content is fantastic, the UI is spot on. Kudos dev for this amazing app. Best $7.50 I"ve ever spent. Thank you.
