Customer Reviews

Great app

I have had this app for a few years and seen it improve gradually to the point that I find myself using it regularly along with myCSC to plan my observing sessions. I really like how easy it is to get observing forecasts for different locations with important details and a much longer forecast than one gets with myCSC.

My new Clear Sky bible

So happy to find this app since Clear Sky Clock disappeared for lack of iOS 6+ compatibility. Not always 100% but when is the weather report ever 100%? Very useful when combined with other weather data. (Look out the window, will ya?)

Best astronomy weather app

I use this app everyday in planning for astrophotography. One feature id like to see would be a rise/set time for the moon based on geo-location. I know you can set a threshold for Moon percentage, but it would be handy for astrophotography. Maybe just make it a widget.
