Love this app. Have used it for a long time and it just seems to keep getting better and better. More features added as time passes making it a "must have". The low cost subscription is well worth it for the pro version. I would prefer a pay once and done, but the price is reasonable for the subscription. It keeps improving in functionality as a subscription should. Highly recommended.

If you are an amateur astronomer, this is a MUST have app. Everything you could possibly need is right there in one convenient place. You get up to five locations on the free version. You get cloud, transparency and "seeing" data in numbers and colors. I've found it to be accurate and invaluable.

countdown timer is broken- I've recommended this app to many friends, but I won't anymore. I understand the reason that you have a countdown timer now. However, if it goes to zero and I try again, then the same thing happens. Btw, I haven't used this app but once today, and got the informational message. Great way to treat someone who was seriously thinking about taking the jump to a subscription. Not any more.
