• Popup images — No need to keep zooming in and out just to see what is out there.

• Full 180 degree display — See at a glance what is in the sky and where without having to pan around.

Great please take my money

This is just great, one of the few Astronomy apps to offer a full 180 deg whole sky view on zoom out, which I personally find the most useful. I bought this over a decade ago and still use it. I would like to send you more money in fact as I feel bad for getting so much out of a single purchase. Please implement an in app purchase so I can tip!

Best planetarium app

Used many planetarium apps. GoSkyWatch remains my favourite. I teach beginners and within a minute they are virtual night sky experts. The Wikipedia link is ingenious.
It is so easy to find anything in the night sky. Just type in the name and follow the arrow.
I also attach it to my smaller telescopes with a phone mount creating a GOTO capability for them. Great trick for finding comets!
The support for this app is also first class.

It's ok for most uses but…

…it becomes a bit antiquated, since there are not many changes coming through. It's also not clear how I can change the view. I'm somehow stuck on the "circular view", which I must've triggered somehow, and I can't fathom how to change it back.

It'd be nice if the app could consider local weather so that it'd better tell me what I see and what not.
