All you guys see many videos on youtube daily on your mobile/desktop/laptop, sometime you wanted a particular video to keep it as offline which you can see it later so for that you use youtube offline feature but it has a drawback which is it can be shareable so in place of that if you use Tubemate then it will more beneficial for you!Feature of Tube mate are-
1-You can see all youtube videos on Tube mate and can search it
2.You can download videos to your mobile/SD card which can be shareable.
3.You can get your videos category wise because it contains more filters compare to Youtube
Now I said as earlier it is good software for mobiles(Android, IOS) and may be available for PC, but it lacks in performance, means in low specification phones it can lag or close or hang or stuck due to some error.It happens sometime not continuously, I tell that because some people complaint about that in playstore comment section and I also experienced that problem so it may be repaired by its developer now.
Overall Software is good.
