Not necessarily. Glutinous Ball's app. Many web novelists were either full-time or part-time. Some were still writing novels. Therefore, not everything was on the Glutinous Ball app.
One of the best apps for novels is Wattpad. It has a vast collection of novels in various genres, from romance to mystery. Many emerging writers also publish their works there, so you can discover new and unique stories.
Another great option is Goodreads. Although it's mainly known as a book - reading community, it has a lot of book summaries and reviews which can be considered as short stories in a way. It also helps you discover new books and authors, which can inspire you to create your own stories.
Well, Archive of Our Own (AO3) is often considered one of the best. It offers a vast collection of fanfictions across different fandoms and has a user-friendly interface. Also, it allows for a lot of creative freedom for authors.
Webtoon is pretty good. It offers a diverse collection of manga and often has exclusive content. Also, it's easy to navigate and has nice features like bookmarking and offline reading.
Comixology is often considered one of the best. It offers a vast collection from different publishers and has good reading features. However, it might depend on your specific comic preferences.
