I think the concept of the app is real good it actually allows you to diwnload anything from youtube, facebook and from all other sources and you can view that offline in your own time.
The design of the app is also very good it is a user friendly interface as well and the functionability of the app is also ok.
But the only thing is that I could not find this app on playstore that is a bit drawback so in that case I have to search for the app in web to download that into my device
Now talking about the usefulness it is hell of a useful app this could just save your day.
I like this very much
