1. The first thing you'll have to do is to download and install TubeMate. For some definite reasons, the app isn't found on the official Google Play Store, so you'll have to get it from elsewhere. The developer warns that there are many malicious apps that claim to be TubeMate, so it has kindly provided a secure list of download locations.
2. If you have downloaded the .apk file using your computer, you now have to transfer that .apk file to your phone/tablet.
3. Once you have the TubeMate .apk on your device, you need to actually install the app. Don't forget to check the "Unknown sources" option found in the settings. Otherwise, the system will not let you install the apk.
4. When the installation finishes, launch the app and find the video you're looking for using the search function.
5. Choose the video, and click on the Download button and choose the Save option.
