For me, MangaPark is quite good. It has a user-friendly interface and a good selection of manga. However, the legality of using free manga websites can be questionable, so be cautious.
One great option is 'One Punch Man'. It's a really popular free manga story. It has an interesting concept where the main character can defeat any opponent with just one punch, but there's a lot more to the story in terms of the other characters and the world - building.
Mangatoon is worth trying. It has a decent collection and provides a smooth reading experience. Some of its features like bookmarks and recommendations are quite handy.
Tachiyomi could be what you're looking for. It's customizable and has a lot of sources for free manga. However, it might require a bit of setup to get it working just right.
Tachiyomi could be the one for you. It's customizable and supports multiple sources for manga. However, keep in mind that the availability of apps might vary depending on your region.
Webtoons is also quite good. It has a variety of genres and often updates with new content. However, the selection might be a bit limited compared to some other sites.
Mangatoon could be your choice. It has a user-friendly interface and regularly updates its manga library. However, the availability of specific manga might vary.
