It is a terrible app, the worst I have ever seen. The reason is the indifference to customers by its creators. The developers made the app in haste, on their hands. Because of this, the program works badly. The same is true for customer support that doesn't want to help the customers with solving their problems. And for all that, they don't provide a refund option. They won't give you your money back no matter how much you ask for it. I think this is a violation of rights. Disliked!
