I use Signtunes with uYouPlusExtra (on GitHub). This does not require a computer, but will cost you 10-15$ yearly to sideload without a computer. But Apple will allow sideloading SoonTM, so it might become free.
uYouPlus is no longer being actively developed, uYouPlusExtra is a fork under active development.
Also perfectly fine, I just prefer the features the uYouPlus app offers. It’s not only ad blocking, but also sponsor blocking, pop out player, background playback, reordering tabs (so I can remove the annoying shorts tab), and a bunch more.
