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 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.

I would appreciate a quick review on the App Store if you are using the app (there will be no popup asking you in the app as I hate those).
Xasteria is available in English, Greek and French.

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.

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.

It tells me everything I need to know about the weather conditions I can expect when planning a night out with the telescope

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.

Extremely helpful in planning astronomical observing runs.

Great coverage of weather for astronomy!
By fuzzyphill
I would love to get notifications when the seeing will be good and clouds minimal.

It works great for where I live in Philadelphia, but when I travel to the Greek islands it's pretty inaccurate

Excellent

Review updated! Thank you so much to the developer for implementing a temporary fix! There was a server problem causing the report not to update. It's great to be able to use Xasteria again.

The best app in the astro-seeing category lets you see lots of information about weather,moon rise set phase,sun rise set and many other useful stuffs. Suggest you download it and enjoy watching stars. ;)

7Timer is down for few months, can you use Meteobule’s astronomical data on this app? It looks Meteoblue's data is more detailed than 7Timer.

I just downloaded Xasteria so I don't know how it will perform long term but it found my location accurately and shows all the data I was hoping it would. I think it will be a helpful tool for my backyard stargazing.
By ctchickens
Xasteria is perfect for astrophotographers to check visibility of the stars to avoid staying up to 3am to find coudy skies. Highly recommend.

Great app, would give 5 stars if it had landscape support.
By Magus Seraph
Great easy to use astronomy app. Simple but all the options you'll really need.
