Some sites even from the megathread of this /c/ doesn't sometimes show health or if it is complete . Also even reccomended torrent search engine websites suck and only crawls through some websites is there any you would rec ? Most traditional ones doesn't work either like DDG, Google or brave any that work ?
Edit : Because of some comments I thought I should mention the tools I use for more better answers
Browser - Fennec with ublock in default mode .
OS - Android.
Client - Libretorrent .
And I would also settle for direct downloads but most sites I've found suck in downloading even with a download manager like they would cut of just for pausing or leaving tab/app, connecting to another app, small network issue, and have more dead links and good ones tend to be taken down fast . So do feel free to recommend ones you use .
Best of luck doing this all on Android. Back when I didn't have a PC I ended up just giving up torrenting. Its not worth the hassle, plus as others have suggested you're going to want to use Qbit, with extensions. Beyond simple QoL things a PC is just going to make everything 1000x easier.
