Rewinding the video by double tapping left or skipping ahead by double tapping right, enabling subtitles, watching in 2x speed, full screen, toggling back and forth without losing your place in the video.
You get no ads but everything else sucks. I haven’t tried sibling’s suggestion for vinegar though, I’m taking about stock with a dns blocker.
all those things work perfectly for me in the browser . Occasioally if you double tap too fast it doesn't like it. but 2x speed, subs. toggling, dbl taps. all work great in safari on ios. I often have 2 or 3 videos that i watch over the course of a few days. I just leave them in tabs and come back to them as i get time. can't do that with the app.
