Ratings and Reviews

A professional astronomy app for the serious astronomers


If you're a serious astronomer, this is a very good app to have, loaded with tons of features not found in many other astronomy/planetarium apps. It's hard to figure out at first because it doesn't follow the design philosophy of Apple (more like the old days of Palm OS which is where it came from) but once you got it, it's very easy to breeze through. Don't buy it if you're a newbie/beginner, it wasn't made for you yet. But when you've gotten good enough at astronomy, come back to this app. You won't believed how much stuff it's loaded with. The author is active and have been releasing updates slowly over the years. "Slowly" because there isn't any thing to improve on but fixing bugs and staying current with newer iOS versions, lol. These days, I used this together with Redshift app and that gives me all the astronomy needs from my iPhone. Planets, satellites, comets, sunsets/sunrises, Jupiter's moons, Polaris adjustments, etc, etc.

No kidding!!


This app is incredible! Not because it is a perfectly written app or because of it's ease of use, it is far from achieving those goal; but because of the shear volume of information packed into this software. I have every astronomy app made on my iTouch and I was overwhelm with the amount of icons to choose from. Heck, I had to consult the Palm OS manual just to know how to save my location coordinates. There is no manual on their website for v3.0 for the iPhone, which is makes frustrating. Normally I would give such an app a lower rating but I want the designers to keep working on this potential masterpiece. If they would at least write an instruction manual for it I would have given five stars.

Bug work around


This is very good astronomy app for the serious amateur astronomer. The tool set is extensive and accurate.
The last update contains a bug in that it sometimes truncates the display if cold started while the iPad is in landscape mode. Until the next bug fix, the work around is to make sure that Astromist is not in memory (open the running app display on the iPad and delete Astromist if it is running). Then just make sure the iPad is in portrait mode and start Astromist. Astromist will preform normally in portrait or landscape.
