Since Apple does not allow direct IPA installs, you must use a "sideloading" tool to sign the app with your Apple ID.
Version numbers like "13426" often refer to older builds or specific "tweaked" versions (such as YouTube++ or uYou+). These are "portable" in the sense that they can be side-loaded onto an iPhone or iPad using tools like AltStore or Sideloadly .
Some recent builds (around early 2026) reported crashes specifically when using the video scroller or timeline. JIT Limitations:
Downloading IPAs from random websites is risky. Malicious actors often modify popular apps (like YouTube) to steal data. Only download from reputable communities (like Reddit’s r/sideloaded or established archives).
