Astronomy teacher:
Still the best

I've taught astronomy for 14 years now and been an avid amateur for nearly 40. I've tried many apps, both desktop and mobile. Sky Safari has always been the easiest and most comprehensive, even dating back to its prior incarnation as Voyager. The current release continues to stand far above the competition. With its three versions, it is tailored to meet the needs of a wide range of users. I recommend the basic level to my students and anyone who just wants an app that can quickly and simply tell them what they are seeing in the sky, whether it be a constellation, star, or planet. Its interface is intuitive and easy to learn for general interest observing, but a little exploration leads to a wealth of educational content and amazing abilities. For friends with telescopes, I recommend the plus version, which goes to much greater depth, and can be used to wirelessly direct many scopes to objects that you might never think to look for, including any passing comets. The pro version is a powerful tool for people with advanced, large telescopes who are doing photography. I can't recommend this highly enough. If you want an app that really works, is fast, easy, and accurate, save yourself the effort of trying its lesser rivals and discovering how frustrating they are. Sky Safari is a worth every penny.

No astronomy app better than this SkySafari

Why is this app better than all others? First of all, the tech support is unbeatable. They constantly monitor our comments and respond almost immediately. Forget your hand controler because SkySasfari does it all: alignment, observing lists, pictures and detailed comments of objects and unbelievable amounts of data on each object, The help section includes the equivalent of an astronomy text book, links to astro sights and local astro events. It is also linked to S&T's SkyWeek app. I attach my iPad to my music stand and watch the sky move in front of me as my scope slews to its location. Passersby are always fascinated with what they see and conversations generally follow. It is also a crowd pleaser for public astronomy events. It is easy to use even though it is complex in what it can do. Without this app your astronomy app collection is definitely incomplete.

Very professional

My dad is an amateur astronomer and he said this was a top of the line product and in tinkering with it it would seem that that holds true. I love all the features and the tiny details. It is a top of the line product just as advertised.

**After using the product for a bit I can see some flaws. I was hoping my father could use it on my iPad but it doesn't have cellular capabilities. So that doesn't help him only my phone can, and on top of that my reception can go out in the deep woods/Mountains and then that mean the app doesn't run as well. Lastly they do an update and expect me to drop another 40$ to get it??? I understand new comers paying a full price but that should really be available for previous purchasers/users as an in app purchase to upgrade for like 4-7$. That whole thing is kinda b.s.
Still a very powerful app and I know they have deep sales every once in awhile. I just think sky safari should respect its establish customers.
