Awesome

Totally awesome

Great

Nice little app to see the weather forecast for observations

Not supported

Does kit seem like they support the app anymore. No updates. App did not update the weather this week.

The Best

Hands down the best forecast for astronomy…ever

The world isn’t just North America

Would have been nice to get a chart for Puerto Rico.

Great Tool

Great tool. I’m a novice at astrophotography so this app / website is essential. And it is great.

Works Great !

I’ve been a Clear Sky user for several years - much more reliable than any other tool I’ve used for astronomical forecasting

Accuracy

Cloud cover about 50% yet says clear Wagoner, OK

Love the app, retired stations still listed

I love the CSC and this app. Recently I discovered that stations β€œretired” from the CSC are still listed and mapped in the app, but the links are dead ends. The OLD Abbey Ridge Observatory (which has moved) and Sheet Harbour. There are be others. The β€œsupport” link does not work, hence this review.

Must have for astronomy!

We have used CSC for over 20 years, and it has been consistently the most accurate forecast out there! Updates occur daily, and sometimes, seems to be more frequent than that. Seldom if ever significantly wrong, and if you want your own map, it is a simple process of uploading your coordinates. My go to whenever considering observing.

Great for everyday use

The only thing that has ever β€œfooled” this app in my experience is marine layers by the coast (Seattle, Oregon coast, BC). Otherwise, amazing tool, super accurate and easy to use once you get the hang of the charts and legend. Highly recommended

Search is useless, missing many locations

I had a 10 year old clear sky clocks program that no longer worked when I updated to new phone and latest OS. It easily found locations near me

This app only finds a limited number of the Clear Sky Sites available on the website, and you have to know the EXACT naming and wording of the entire clock title.

Clear sky locations I’ve used for decades aren’t in this app’s list.

Useless, wish I could give it Zero stars.

no key to charts

it may be accurate, but with no key to the charts, who knows what color is what. If you're new to Astronomy, it's pretty much useless.

It works and it is easy to use

Easy to understand and use - nicely functional app!

NO TOO IMPRESSED

This version for my iPhone doesn’t allow me to pick/select favorite locations. In fairness the version I have on my Mac works fine.

Please add widgets and iPad support

I love the accuracy of the forecast but I really wish there was iPad support and support for Widgets in iOS.

ABSOLUTE NECESSITY FOR ASTRONOMY

This is my first, and often only, go-to for astronomical seeing details. It’s fundamentally necessary.

Clear Sky Chart

Simple and useful.

Awesome

This is great weather guide fo clear skies. It is my go to app for star gazing. Very accurate. Highly recommended!
