"Every amateur astronomer yearns for clear, dark skies, and this exhaustive app helps you find them."
- Sky At Night Magazine 2017

"Several astronomy-oriented weather apps are available, but Scope Nights has become my favorite… it does a fine job of summarizing the data in a clear and understandable fashion."
- Sky & Telescope Magazine 2015

"Conventional weather forecasts meet the needs of Earthly dwellers; news of cloud cover when sensible folk are asleep is hardly required. Now via this wonderful App… local forecasts for nocturnal weather… are now available."
- Astronomy Now Magazine 2012

Indispensable for amateur astronomers


I use this app to plan all my observing sessions. It has all the information that I need in one place, not only informing me if it’s going to be a clear night but also what humidity to expect (important because high humidity may fog up your telescope) but also the moon phase. You can set the parameters that could limit your particular observing requirements so that it only gives you the “green light” when all the conditions are just right. Excellent.

Moon rise and set times

Steve Something

Edit: Initially gave four stars. The feature I'd have liked to have seen added has been included in the 2.5 update. Looking forward to testing it out. :)

Original review:
A good solid app, but it would be a great improvement if it gave to rise and set times for the moon.
If you're wanting to pick a night with no moon, the app will happily point to a night with a new moon, but completely ignore nights with a full moon that's below the horizon.

Accurate weather & Dark Sky info

When youre Young

This is a great app which allows you to store your favourite sites and get good weather information to aid viewing especially good here in the UK where the weather is so changable. The only thing I would like to see is the ability to place a pin on the map to store specific locations more accurately. Takes a bit time to learn how to navigate, but highly recommended for us cloud chasers!
