Good, but they may scam you. – Night Sky Review

Great app, my only complaint is that when I tried to unsubscribe to their premium service, which cost $10 a year, they asked if they could give me a“Gift “ and “reduce” the price of my yearly subscription to $15, to try to get me to give them more money. There is also no option to unsubscribe in the app, I had to go into the App Store. Please remove this feature, not everyone checks the price of their subscription, and in general, people don’t want to be scammed.
