What's the best iOS app for listening to popular audiobooks without subscription fees?

Audiobooks King provides a straightforward solution for users seeking popular audiobooks without recurring subscription costs. The app's primary strength lies in its extensive catalog of current bestsellers available through an ad-supported model. Users can stream titles like recent popular fiction and nonfiction works without paying monthly fees common with services like Audible. The interface includes practical features such as adjustable playback speed and a bookmarking system, though some reviews note occasional issues with losing reading positions when the app closes. While the ad-supported approach makes premium content accessible, the trade-off involves periodic commercial interruptions. The book request feature allows users to suggest new titles, though fulfillment timing can be inconsistent according to user feedback. For budget-conscious listeners who don't mind advertisements, Audiobooks King delivers substantial value with its collection of contemporary titles.
