I was earlier using tubemate application but I noticed that its downloading speed is getting low then I heard about snaptube and thought to try it.I installed it and download few videos and it gave amazing speed upt 17mbps in good network conditions I have downloaded many large files from snaptube 600mbs and it has worked well.It saves time and downlods faster than other apps .so u may try it .: -) im still using this app and this app is working pretty good.
