10 Best Astronomy Apps for iPhone

Long gone are days when astronomy was only a telescope stargazing experience. With today's technology, we can experience the night sky like never before. Although astronomy equipment is not cheap - telescopes, astronomy binoculars, telephoto lenses, mounts, specialized cameras, high-end computers, etc., you don't really need them to admire the night sky (but of course they are perfect examples of the best astronomy gifts for stargazing lovers) — you have your astronomy and astrophotography device right in your pocket. Today I will show you my personal Top 10 Astronomy Apps for iPhone - including Astrophotography and Stargazing apps.

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.
