It works but you don’t really getting a lot of value

When it was first installed, I got lots of errors about not being able to save location information. Sent a tech support request and got nothing back. The error is now gone but it doesn’t always save my location but I guess my biggest grip is you don’t really get anything that isn’t already free with other apps. It has potential, but hey seriously need to add more features for the price they charge. I guess that is why there is not a trial version.

Needs work

I use an app called “Good To Stargaze”, which is free, and for a nominal fee allows one to save 5 sites. That app is very succinct and intuitive in its forecasts and presentation. Scope Nights offers much of the same information, and has a more colorful interface, and it has some basic stability issues. When connecting to the Internet to get weather information, the app can hang. When the connection times out, it sometimes crashes out to the “Finder”. I like that you can look up known dark sky sites and observatories, and add - evidently - dozens of custom sites. However, when the app is new, it seems to store every map position you navigate to, and your current location is stored dozens of times, and you cannot add new sites because the max number has been reached. I manually deleted all of these sites, which took several minutes (needs a delete all interface), and afterward it worked as expected. Not recommended over Good To Stargaze, and it does mostly work, but has the drawbacks mentioned above.

Wish I’d have found this sooner

I used to use ClearOutside, this is the same idea but actually works. Even for random locations in tiny towns near the desert I get so many location results. ClearOutside couldn’t even find major cities or counties I put in. Icons are great, really easy to understand, and hourly forecast on specific nights make it really easy to find key times to go out. I pair this with PhotoPills to plan my shots of the Milky Way and other nightscape scenes.
