Xasteria Overview
If you would like to support it, as well as fund the 7Timer service behind it, you can get Xasteria Plus, which can access non-free weather sources and has some extra features like night vision mode, iPhone landscape view, lunar calendar, location manager.
The app has been extended to offer you quick access to all of your favourite weather resources and tools: Clear Sky Charts (for North American users), Clear Outside, Meteoblue, Windy, Astrospheric, Sat24.com, the latest water vapor satellite images and even light pollution maps.
The main forecast source, 7Timer, is based on the NOAA/NCEP-based numeric weather model, the Global Forecast System (GFS) and gives you a forecast for the entire globe with a resolution of about 20km at 3-hour intervals.
Xasteria was originally created to bring the excellent Astronomical-oriented ASTRO weather forecast of the service 7Timer to your iOS device.
Xasteria provides you with a choice of 3 visualization modes for the data: the new 7Timer! ASTRO graphics, the color-stripe graphics similar to some other astro-forecast services and a raw text mode.

My Go-To App for Astro Weather
This is always the first app (and often the only app) I check to plan what nights I should pull out my telescope. It does a brilliant job of making it easy to see astronomically related forecast data from a variety of sources (some of which have no mobile apps), allowing me to easily compare to see what the forecast really looks like.

Favorite app to plan observing
this app has become my go to app to plan observing sessions. Over the last three years it has continued to improve so that I now turn to it first. The improvements I value most are improvement of its weather prediction, incorporation of link outs to other prediction models and several smaller usability improvements.

Intuitive with clean interface
Only gripe is that low clouds aren’t shown on main screen, which is useful in foggy areas. That said, the alternate forecasts do, so still giving 5 stars.
