Strelnik, you should be aware of application like these that at the first sight a free to use, and then it is trying to charge you for money. If I’m not wrong, that one should charge you monthly. I don’t see any sense in using such an application, I mean to pay money for something that can be done for free, that’s so stupid. You can have a look: youtube to mp4, and make a try, probably that’s what you need. I’m using it whenever i need to download song on my phone, to listen music when i’m on trips or don’t have internet conection to use soundcloud. As a advantage you’ll see that that there a lot of option to converter videos.
