I really enjoyed this app when they had a promotional offer. Its a great app for those interested in whats in the sky above. BUT I could not keep them from an unauthorized charge to my bank account. I have the video showing how they "said" you had to cancel. But I could not. When you have a business practice like this to scam money from people, well, you don't deserve to be in business in the first place. DO NOT BUY OR GIVE MONEY TO THIS APP NOR THEIR COMPANY.
