VLC for iOS is just as essential as VLC for your Mac/PC. It’s simply the best video player there is.
This app bugs out every once in a while, but I find most of the glitches can be solved by killing the app and relaunching. I’ve been using VLC on my iPhones for years (and even longer on my computers) and love it.
Also, just like with the desktop version, it is easy to adjust the audio delay within a video in case the sound of a video is out of sync. Click the clock icon to get to the audio delay tweak settings.
