Am using tubemate for several years, its one of the best video or audio downloading application for android. I mainly use it for downloading music. This application is able to convert videos from popular websites like youtube, dailymotion, facebook, twitter etc, to music files like mp3, ogg and m4a. The sound quality of music files is amazing. It can also download video files to different resolutions like 144p, 360p, 480p, 720p and 1080p and also to different formats like 3gp , mp4 etc.Tubemate has inbuilt web browser which makes this application more userfriendly. Its easy to use, I dont know , why its not available in google play store now. But, you can simply download it from their own website. From my own experience I would like to say , if you are looking for an application which can download good quality video or audio files from internet then go for tubemate. Thank you.
