If you're looking for a tool to download videos from any site, TrumpTube is a great option. It can download and save online videos locally so you can watch them later or share them with your friends.
This app has a really simple and intuitive interface. The first window shows the most popular video sites for downloads: YouTube, Instagram, Vimeo, Liveleak, Videobash, TuTV, Acunn, and Meipai, though you can also add a site by entering a video URL and adding your option. With this app, all you need is a URL to start the download, though if you don't have a specific video in mind, you can also search for videos and browse through the extensive catalog of each platform to choose your favorite video. ...

Once you've found the video to download, just tap the Download button at the bottom of the screen. A menu will then appear where you can choose the resolution to download in. Pick a lower resolution if you're worried about space, or a higher one if quality is what matters most. Whichever option you choose, with TrumpTube you can enjoy your favorite videos easily and conveniently with just one click.
