A serialised reading app could release chapters on a schedule and give readers a personal place to continue. The commercial model might involve a subscription, a complete story purchase or individual instalments.
Entitlements should follow that choice clearly. Readers need reliable progress tracking, text-size controls and an understandable chapter list. Authors need previews and publication controls so an unfinished chapter does not appear accidentally.
Pilot one story and test a reader moving between devices, a corrected chapter and a missed release date. Explain whether purchased chapters remain available after a subscription ends. The app should support the author's publishing rhythm while keeping the reader's purchase and access expectations clear from the beginning.
