Great app, but has some inaccuracies
First, the bad: This app is a lot of fun, but I'm having trouble trusting everything it's telling me. Most of the really far away deep sky objects have very inaccurate distances displayed. The Andromeda galaxy, for instance, is labeled as being 630 LY away. It is, in fact, 2.5 million light years away. The Sombrero galaxy? The app says 630 LY again, but it's closer to 29 million. 630 LY ISS still very much within the Milky Way. That data is aggressively wrong. The good? Everything else. It's fun exploring the solar system, traveling to stars like Betelgeuse, visiting the dwarf planets, etc. I'm an astronomy nerd, so despite those glaring errors, it was still immensely exciting.
