I know this is not a Christian community, but I recently discovered Tachiyomi looking for alternatives to Saikou and a good alternative to read manga (which I don't do much, but it makes me curious) is Tachiyomi and although installing extensions is really simple the vast majority have NSFW content (or hentai?) and Jesus, I want to look for Pokemon manga and if I install extensions randomly I end up finding things I'd rather not have seen before, and many SFW extensions "don't work" or give an error that something went wrong.
Xirup's phone is hentai free. Lookin for it? Leave.
Jokes aside, mangakakalot, mangalife, and manganato seem to work well and have a wide selection. If they're not working for you, maybe try a fresh install?
If you're delving into bootlegs, you might just need to be prepared to run into NSFW content, though.
