"SkySafari is the standard bearer of astronomy apps. I have used other programs and apps in the past, but SkySafari fills all my needs for great user interface, exceptional information, great graphics, and east of use. I am a long time user of previous versions of SkySafari, and this one just improves upn a great program. I use SkySafari to plan my observing sessions, control my scope wirelessly, record my observations, and research the properties of what I am observing. The amount of information available in this program is simply amazing."

"The first thing I notice is how responsive it is. Panning and zooming around the sky happens at a much faster rate than my other programs (no, I'm not going to name them). Second thing I notice is how easy the interface is to navigate. Each icon has a label underneath, but it's clear from the icon what each button does... Having integrated with Apple Maps (such as they are), and S&T's Week at a glance are handy... And finally, the developers are very responsive to issues and feature requests. This program is highly recommeded!"

It's more than a star chart - it's a celestial travel guide!
