Be very careful
Let me say that I love this app. It's perfect for making short video clips of pictures. That said, it is not good at keeping track of your account. I paid for a "lifetime" subscription that offered "unlimited" use of templates. This is not accurate. The app will give you enough credit credits weekly to make 17 short videos of your pictures. You can purchase additional credits though sometimes they will post and sometimes they won't. Overall, the app is very poor at keeping track of credits. By my estimation, they owe me 5000 credits (give or take a couple hundred). They just charged my account again, and yet failed to put any credit credits into my account. I've contacted them on three occasions: they replied the first time and said they would sort out my account. It never happened. Two subsequent emails have gone unanswered. Long story short: the developer's extremely poor management of user accounts makes what is otherwise a fantastic app essentially useless.
