Pros and cons of SkySafari 4: Journey into Night! Explore Sun, Moon, Mars, Stars, Satellites, and NASA space missions! app for iPhone and iPad

SkySafari 4: Journey into Night! Explore Sun, Moon, Mars, Stars, Satellites, and NASA space missions! app good for

Great app; Ive used this for several years now and continue to appreciate it.
Really nice little app. Because of it I saw the ring of Saturn with my telescope today for the first time
Good and informative. The compass mode is very comfortable and intuitive for finding objects.
Really good app wish the orbit was free but other then that I love using it
This is a fun app to use, just to read up on stars and planets. But its also great in the field for trying to locate objects, planets and stars.
Has worked well and encourages us to go outside at night and look up on occasion!

Some bad moments

This annoying problem is i guess with the "current time" and "current location" buttons. (i have ios 7 In my ipad)...even if you select them, they get deselected themselves automatically. i live in istanbul / turkey (+2,00h from GMT) but the app sees me in -8,00 gmt... completely wrong sky view... the su starts to shine at night and moon rises in the morning... my previous comment hasnt been published yet. anybody there to help me? i cant reach the support page...this is urgent because best clear winter skies are passing but i cant use this app which i PAID MONEY for...
"Compass" doesnt work, half of the screen is often black and there are other bugs in "settings". Its a nice app, so, pleas, solve the problem.
This is an amazing app. It gives you enough to actually know when to get up to see something, asteroids, eclipses, etc. Simple to use and yet filled with detail information.
The only thing I dont like about it is that, compared to Star Chart and Star Walk, it crashes too often on my iPad. Otherwise, its my favorite star app.
I bought this app for my honeymoon safari in Tanzania so I could observe the night sky above me as I was going to be in a country with very little light pollution! This app is intuitive, informative, and beautiful. Highly recommend and it works great. Its literally the only app Ive ever spent money on and is well worth it!
When we go camping - this is the app I open up at night to tell me what I am looking at. Plus on clear nights here at the house we use it. The other week our 10 yr old wanted to go out with my phone and use this app all by himself--- we all enjoy this app Very much !! So helpful and user friendly for I am no techie!!
