Zero prediction reliability - don’t waste time

Been trying to use this for years but it has a perfect zero reliability in Predicting cloud cover in the northeast. If I could give it a zero I would. I’ve put in Reports of the issue but what does the app developer do, nothing but think you should now pay for the worst forecasting imaginable!! Do t waste your time or money.

Three forecast models combined!

I love this app! It is my go-to for checking the astronomy forecast. The free version provides a highly detailed forecast based on the Canadian weather model. The forecast is updated every 6 hours. The detailed forecast covers roughly the next three days. (The extended forecast goes out much farther but with fewer details and that is understandable because it is much more difficult to predict.) The 'Pro' tier (in-app purchase) combines two additional models to produce an "ensemble" forecast based on Canadian, North American, and European models (color coded so you know which model is forecasting clouds). I can't count the times I'd check a forecast, get the all-clear, and show up to a cloudy sky. Thanks to the ensemble forecast, if all forecasts agree that it will be clear ... you are probably in the clear. (The Pro tier is also ad-free) The ensemble forecast feature is also available to astronomy clubs and star parties at no cost if you qualify (that tier still has ads but you do get the ensemble forecasts). It is nice that the author extends this to clubs and star parties that do public outreach to share their passion for the night sky.

This is a subscription app, not a purchase app

I don’t like paying subscriptions. I’ll only make a onetime purchase. It’s just not worth a subscription for occasional use. Deleting app.

Powerful and easy to use!

Interface has an amazing amount of data at a glance. An irreplaceable resource to help me figure out where and when I can shoot with my telescope.

Fantastic app, it was built with love and intention. Works like a charm.

I love this app, but the cloud motion aspect is terrible sometimes even with a good cell signal. For example, I can watch a Netflix movie on my cell phone right this moment, but the animation part of Astrospheric won't work. This is unacceptable for those of is that take our astrophotography to remote dark sights. This aspect really needs to improve.

Very useful, but getting ads

I really like the usefulness of this app. I don’t waste time putting up equipment and can plan my astrophotography sessions with a good deal of confidence. My only complaint is I have a pro subscription but continue to see ads. What’s up with that? Would have given 5 stars otherwise.

My go to Astrophotographer app!

Maybe more detailed?

Love the app but would be nice to see the components that go into the seeing rating.. and also might add at least jet stream speed.
