How do you not have Sky Guide on here!? It's far superior and a better UI than Night Sky, Star Walk 2, Redshift Pro, and SkyView Lite.

What about Stellar Tour? It's the most comprehensive astronomy app out there, covering all scales of astronomy with 100s of images. It has a beautiful AR stargazing experience with millions of stars, as well as the cosmic web and cosmic microwave background in AR. It's one of the only apps out there created by an astrophysicist with expert knowledge of astronomy.
