Concept of the app is quite good but its response is too slow. It hangs often and freezed my phone too. Download function does not appear often and is not user friendly. Download is so slow that its better you watch the video online so the app is also not much useful thought it has features to just count. Since is told you app is not user friendly its design part is very weak. I would like to rate it not more than 2.7 star out of 5.
