HiTube

HiTube is an app that lets you download any video from YouTube without problems. The only thing you need to do is browse YouTube directly from this app, and when you find the video press the download button. That's it.

When you do that, the video is automatically added to the download queue, and then to your Android's memory. The videos are downloaded in 3GP format and low resolution by default, so they take up less space.

In the settings, you can choose which type of videos you're interested in – movies, video games, music, series, etc. – so you can quickly find what you want to download. You can play these videos on any app that supports the format.

HiTube is a powerful app for downloading videos from YouTube. You can save lots of videos from this platform on your device. Competition is very high for this type of app, but it's always good to have a decent alternative.
