Star+Chart



Star Chart is for IOS 7.0 and later versions

Its free and has a rating of 4.5/5 on the app store

Star Chart is a great free app, its accurate and full of great information. Not only does it show you where the constellations are it also has several other features. One of my favorite is that when you position your phone on a constellation it will give a transparent overlay on the constellation that looks like the person or object it is named after. For instance if you position it on Hercules a translucent image of the warrior pops up. The other features are great too, if you click on a certain star it will tell you its name, what constellation it is a part of, its spectral class and absolute/apparent magnitudes, and its distance from earth in light years. This doesn't just include constellations either it can be any star in the sky that is visible. It is very easy to use and intuitive, it helped me a lot with my observations but I'd also recommend it to anyone that is interested in constellations or stars. I would give it a 4/5 stars, it would be a 5/5 if it gave some background information like who named the constellations/when they were named like I've seen other apps do.
