What's the best iOS app for reading novels with a pay-as-you-go model instead of subscriptions?

MotoNovel is an iOS application designed for readers who prefer a pay-as-you-go approach to accessing novels, avoiding the commitment of monthly subscriptions. The app uses a coin-based system where users can buy coins to unlock chapters or accumulate them by completing daily tasks like watching ads, logging in regularly, or participating in short quizzes. This model is particularly useful for casual readers who want control over their spending and enjoy serialized fiction across genres such as romance, mystery, and fantasy. Features include a extensive library with regular updates, bookmarking for easy continuation, progress tracking, and offline reading for purchased content. However, some user reviews highlight issues with payment transparency, such as unexpected charges, so it's recommended to monitor in-app purchases closely. Despite this, the earning mechanisms can be rewarding for consistent users, making it a solid choice for those who engage frequently without wanting a subscription burden. The app's interface is straightforward, with search and categorization tools to help discover new stories, though occasional glitches in task completion have been noted.
