ViDL is a YouTube download app for Mac. It comes from Ole Moritz, developer of the amazing Pythonista and Editorial iOS apps. ViDL is a simple wrapper for the youtube-dl command-line tool, so if you already use that, you don’t need this. But the app is far easier to use than a command-line tools. Plus, it offers a built-in browser, in case you need to log in to a site to get access to the target videos. There’s even a ViDL Safari extension.
