Great Start!

I have used TheSky for over 20 years and glad to see it finally on iOS. Certainly not as glitzy as some astro-apps, but like the desktop version it is designed for serious astronomers. Can't wait for the Pro version and scope control.

Not a good mobile application

I have been using TheSky X on a macbook pro for a few years, and more recently SkySafari 3 Pro on an ipad 2 for the past couple of years. TheSky is an excellent macintosh app, but it doesn't work as a mobile application.

The fact that this app is only available as for ipad, not iphone, is a big hint that Software Bisque haven't figured out how to present images and information on a small screen. The text and icons are all too big and opaque, so they obscure the stars. The process of selecting an object to get more information is cumbersome and counterintuitive (in ios you tap on things to select them!), and once an object is selected it's completely hidden behind TheSky's big red bullseye.

The app as currently configured lacks many functions available in competing planetarium apps. You can't orbit Jupiter to see where the moons are in their orbits. You can't control your go-to telescope from the app. The sky looks like a printed atlas, not a realistic starscape.

TheSky's great strength is the information it presents about the stars, including spectral type, proper motion, etc. You can even get a plot of each star on the Hertzsprung-Russell diagram. If you're a serious student of astronomy, I would suggest purchasing this app as a secondary reference to have at hand at the telescope, but I can't recommend it as a primary planetarium app.

VERY Disappointing.

There are several issues.

1) A major problem is that when zoomed in to anything less than a 60º field of view the stars each become a separate red and blue circle, almost like a 3D image.

2) There is no apparent way to adjust the brightness of the alt-az grid or the labels; they are so bright compared to the sky image that the app is barely usable.

3) Magnitude settings seem to make no difference in the number of stars shown.

4) I have an iPad with retina display. This app looks does not have the sharpness that SkySafari does. (The Splash screen looks great, and so do the toolbars, but the sky display itself is bad, appearing almost pixelated.)

Is there any way to get a refund? This app is definitely not worth $4.99 or even $.99

I'm hoping for a quick update to fix these issues; I really wanted to like this app.
