This app is worthy of the current 4.9 star rating and my 5 stars. It's so easy to install and then you're watching a video and all of a sudden it jumps forward a minute or two to miss the sponsored promos YT creators insert into their videos. The first few times I had to rewind to make sure SponsorBlock had got it right, and sure enough it was correct to the second. I no longer question it when SponsorBlocks skips forward in the video as it is always so accurate.
