Lezhin Comics sometimes has free manhwa available. It has a diverse selection, but you might need to keep an eye out for promotions and limited-time offers.
I'd suggest looking into apps like MangaToon or Manta. They sometimes offer free access to manhwa. Just make sure to check their terms and conditions for any restrictions.
You might want to check out Manga Rock. It has a decent collection of manhwa, and there's a chance you'll find some free ones. Just be aware that the legality of certain sources on such apps can be questionable.
Honestly, it's hard to find a completely reliable app for free manhwa. You might come across apps like MangaZone, but there's no guarantee of the legality or the frequency of updated content.
Another option is Libby. It's an app that lets you borrow e - books from your local library for free. So if your library has a good selection of novels, this is a great way to get them without paying. All you need is a library card.
Several popular free reading apps were recommended, including " Listening to Books for the Lazy,"" Listening to Books for the Whole People,"" Listening to Books for a Hundred Listening," and " Listening to Books for Dolphins." These apps all had rich audio resources and complete categories. They supported functions such as multi-speed playback and timer settings. Which one was better depended on one's personal preference.
