I think Comixology is a great option. It offers high-quality scans and has a user-friendly interface. Also, it often has exclusive content and updates regularly.
I think specialized manga apps such as Tachiyomi and Manga Rock are great. They often have updated content and customizable reading settings. However, make sure to use legal and authorized sources to support the creators.
Many Chinese novel fans also recommend Z - Library. It has a vast collection of books, including Chinese novels. The advantage is that there are a lot of free resources available, but it's important to note that the legality of some of its content has been questioned in some regions. Make sure to abide by the laws in your area.
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.
You can find free novels on QQ Reading, Xiaoxiang Academy, and other platforms. I'll recommend some free novels for you: " Douluo: Star Dou Forest signed for a hundred thousand years "," Ten Thousand People in the Cultivation World Survive, I'm Forced to Conquer the World "," Starting from Douluo to sign for the Reincarnation Eye ", and so on. I hope you like my recommendation.😗
