I love it! I have used the desktop version lots and this mobile version is just like it. Stellarium is the only astronomy app I know that labels the navigational stars, which is great if youre learning celestial navigation.
You have to explore the icons a little bit to become familiar, but then its quite easy to use. I love the night mode in red, which the desktop version lacks.
I agree with the astronomer who reviewed: this version needs the ecliptic. Also, showing the celestial equator would be helpful. As well, in the desktop version, the atmosphere condenses at the horizon. This means that even without a ground, you can see where the horizon is located. But those are just tweaks to improve an already good app.
Thanks for making this mobile Stellarium!
