Find the TubeMate application:

Within the existing options, we tap on Uninstall.

Now, we confirm the uninstallation by tapping on the OK button and wait for it to disappear from our device.

From the application drawer look for the TubeMate app and make a long press until a pop-up menu appears in which we tap Uninstall:

In an instant, our application will have completely disappeared from our device.
These methods are usually clean, although it is true that sometimes they leave residues and data inside the mobile. To do this, we can use specific cleaning applications, or in the case of having Xiaomi, the app of the device is pre-installed. These programs ensure that, in addition to uninstalling the application, they remove any data or residue left in our Android. However, all the videos that have been downloaded will not be deleted and will remain in the memory of the device.
Normally from the Google Store, you can uninstall the applications installed on our device. TubeMate, being an app that downloads videos from YouTube, owned by Google, is not within Google Play, so it can not be uninstalled from the store.
