This app is divided into boxes that represent different social networks. If you want to download something from Facebook, for example, you have to go to that section. Once there, search for the thing you want to download and select it manually. Press on the arrow icon and a menu will drop down from which you can choose the download quality for the video. The better the quality, the more space it will take up on your memory.
From the AyaTube Video Downloader download window, you can see at a glance what you've already downloaded. That way, you won't download the same video, and you'll also have everything you've already saved readily accessible. Enjoy your favorite videos from any social network with this app.
