I bought this and I could see the nice sky, stars and planets. Especially , I love the sunrise and sunset color changing, that's awesome, and the astronomical facts that I could every time I double tab the screen. The night sky is very beautiful.
Wow, I could choose any of my apps on my tablet to pop up notification to open automatically during sunrise and sunset . Now I set my calendar pop up during sunrise and music during sunset.
The constellations that visible only in the night is good too.
