Downloading videos is now as easy as 1-2-3. But you need to have a Wi-Fi or data connection to do so. If you don't, you'll have to turn on your cellular network to use this app.

The first step is to open the app and enter the URL or video you want to download. 

After that, you just need to choose the resolution and the size. The default option is the best option for most users. But you can change it to a lower or higher resolution, and the higher resolution will give you a better quality.
