Which Android app offers a good balance of free and paid manga chapters without a strict monthly subscription?

Comikey is a digital manga and webcomics platform that employs a hybrid monetization model, distinguishing it from strict subscription services. The app uses a 'keys' system to unlock chapters. A key is typically consumed to read one chapter permanently. For users seeking to minimize spending, Comikey offers multiple avenues: daily free keys are granted for each individual series, and watching video advertisements can provide access to select free chapters. This structure allows readers to follow several series concurrently without a recurring financial commitment. The image quality and app performance are generally praised in user reviews. However, the experience is slightly hampered by a notable omission in the reader: the lack of a double-tap to zoom gesture, a standard feature in many competing apps. For budget-conscious readers who prefer a pay-as-you-go or ad-supported approach over a flat monthly fee, Comikey presents a viable and often generous alternative. Its model is frequently compared to Webtoon's daily pass system, but with the added benefit of earning bonus keys for every five purchased.
