Features

uYou: uYou has a ton of features that I can't list them all. Visit here for more info!
iSponsorBlock: Skips annoying sponsor ads inside videos. iSponsorBlock is based on SponsorBlock engine. Basically, this is the iOS version of the SponsorBlock extension.
YouPiP: enable YouTube's native PiP. More options are in YouTube Settings - General.
YTUHD: unlock VP9 codec and in effect, enables video quality of 2K and 4K. You can enable/disable YTUHD in YouTube Settings - Video quality preferences.

And many more...!

YTAutoFullScreen: autoplay videos at full screen.
YTClassicVideoQuality: since YouTube v16.xx, you need one more step to change the video quality. YTClassicVideoQuality brings back the old video quality selector, which is a lot better than the new one.
YTNoHoverCards: offer an option to enable/disable the annoying suggested videos show up at the end of the videos.
YTNoCheckLocalNetwork: block the Local Network permission popup.
YouRememberCaption: make YouTube remember your video caption setting (if not already).
NoYTPremium: remove YouTube Premium upshells.
YTSpeed: add 2.25, 2.5, 2.75, and 3x playback speed
YTMiniplayerEnabler: enable Miniplayer for all YouTube videos.
DontEatMyContent: Prevent the notch/Dynamic Island from munching on 2:1 video content in YouTube.

uYou: all known-issues of uYou are listed here. Make sure you take a look at it before reporting any bugs! Also, keep in mind that uYou+ is a modified version of uYou, DO NOT bother MiRO92 with problems unrelated to uYou!!!
Issues that related to uYouPlus are here

uYouPlus (or you can call it uYou+) requires iOS or iPadOS 13.0 or later. The latest version of uYouPlus can be found in the Release tab.
For AltStore user:
- My official AltStore repo: https://qnblackcat.github.io/AltStore/
- Open in AltStore (v17.39.4-2.1) - It will take a while to install because AltStore needs to download the IPA.
