Tubemate is not on Google play store, I searched the net and found this app , It works as youtube app but gives you green arrow option to download the video depending on your choice of resolution size and it even gives you option to convert into mp3 I have tried both and software is tested verified by me, there is no virus in it, you can easily download from my 4shared account linked account .
Download Tubemote APK file
Click and Install it .
Move it to SD memory
Open it and browse youtube search video
click the the video you have searched , you will see green arrow click
it will prompt you play or download click download
resolution depends on you ,
it will start downloading the video once done it will be in your videos
if you want to convert video into mp3 clicking the file to download instead of video scroll down and click mp3
it will download as mp3.
very simple and good app.
keep checking I’ll be adding more apps ( APK ) directly which are Cracked and not on Google Play.
