Ratings and reviews

Can't give it more than 3 stars as the developer has not posted in an easy to see it place a note that the app is not global, coverage being only for USA and Canada. He has put it somewhere in the fine print. It is misleading and unprofessional, all the more once you pay his 1 year paid plan, 1 hour later there is no cancellation/refund, in contrast to many other apps where if you cancel within 24 hrs you get a refund. With such an approach even 3 stars are too many.

This app is fantastic! It has very detailed and accurate information about forecasted cloud and atmospheric conditions, weather, wind direction, and more that make it invaluable for astronomy, stargazing and astrophotography. I have yet to find another app that packs so much versatility and information into such a clean, easy to use package, and all for free! I highly recommend it!

Every ad (of which there are many) has a close button, which does not close the ad, but instead takes you to a page where you could "subscribe" to this service. Why anyone would be fool enough to subscribe to a UI populated with data the author is obtaining for free is beyond me. Shameless money grab there, which is a shame because the UI is nice. I would one time purchase it for a reasonable price, perhaps even the yearly price.
