*2024-07-14*

Could you add more objects to be a better app for me?

### 1/5 — Can't control iPhone.

*2024-05-02*

When I open this app the screen is completely full with the app. I cannot swipe up or any direction to close this app. I had to restart my iPhone in order to close this app. This is the only app I have ever experienced this problem with.

### 5/5 — Universal!

*2021-07-19*

I loved that your 2008 channel hit 1,000,000 subscribers and the solar system!

### 3/5 — Good

*2021-07-06*

Even though it’s a great app. I rate it 3 stars because of a few errors with the description of a few objects, some of the words are cut off from the end. Also, some of the information is pretty old, maybe even older than the app like the largest star. If all of this is updated, it would be absolutely perfect.
