Absolutely brilliant. I have been waiting for this since I lost starry night on my computer. Fantastic app for such a great low price

It is handy to have for planning when I am not near my desktop computer, and helpful in the moment while stargazing and looking for other objects than what I wrote down. The coordinates are available for more objects than I will ever see. It shortcuts the time in finding a specific object using the compass feature. I needed the ability to find Polaris through trees, rooftops, and other obstacles so I can properly align my equatorial mount and the search/locate feature does that. I suggest reading the user manual and FAQ on their website to get the most from the app. I find certain display items like the equatorial plane, merdian, and RA/Decl grid very helpful, and the red screen is a MUST HAVE item. I also love the ability to change the time reference. If my scope was a GOTO, I would use the scope controls. You get an awful lot for this inexpensive app, made by the same company that does the phenomenal Starry Night desktop/ laptop software. It is worth the money.

They have provided a revised version of the app that no longer crashes under ios 8 (at least on the iPad). Thank you!

This is a very well crafted application. Beyond the photo-realistic sky that it presents, the Plus version allows me to control my iOptron telescope using a wireless connection! A very feature-rich application that is easy to use. Five stars!

I was a big fan of Voyager, the ancestor if SkySafari. I use SS for planning observing sessions, creating observing lists, and telescope control of the Sky-Watcher SynScan telescopes I have access to. Very satisfied!

Amazing tool for amateur astronomers! Very usefull to plan your night of observations.

Some bad moments

Doesnt seem to want to follow phone movement very long and usually shuts down in less than a minute.

I can no longer use the compass feature after the latest update that "improves" compass function.

Every imaginable feature seems available in clear and obvious for functionality. I would appreciate more direct and continuous control over forward and backward time. I cant think of anything else to complain about.

The heading says it all. I am no expert but this app has all the bells and whistles Ill ever need. To correct a previous reviewer who cant get compass to work: on your device settings scroll down to the app and open location then check to see that the location is in the "on" position. Then it works fine.

I have had this app several months. When out at night, I know what Im looking at. It is never asking if I want to upgrade. This has everything and more than I need. Very happy I paid a little more and got this app.

I bought the Plus version. Its the most Ive ever paid for an app. It is worth the cost. Powerful, easy to use, and the Help text is very good and the customizability is extensive but strict forward. I use this more than the program on my PC I spent hundreds of dollars for. I use it to guide my telescope and it is very easy and intuitive. I also like the ability to create custom observing lists and record observations. The information and pictures of each object are informative and interesting. Many if not most have accompanying detailed photos.
