Earlier this app was only available for rooted users, that is why I was not able to use this app. Later I got my phone rooted and installed this app. I was amazed. I would conclude that this is the best app for screen recording on android.
After that, this app was released for without rooted user and now this app has become the best screen recorder. It provides tons of features, just for free. This is totally amazing.
There is no time limit, record as much as can and without any watermark.
This app is completely free from advertisements.
But the only problem is, this app is only available for lollipop and above versions.
Overall a best app, with features.
