Which Android app lets you earn free reading currency by watching ads?

INKR — Comics, Manga, Webtoons is designed for readers who prefer earning content access through ad engagement rather than direct purchases. The app's ink reward system allows users to watch short video advertisements in exchange for virtual currency, which can then be used to unlock chapters across manga, webtoons, and comic titles. This approach works particularly well for casual readers who don't mind occasional ad interruptions in return for free access to premium content. Reviews indicate the system generally functions smoothly, though some users have reported occasional glitches where rewards don't immediately register. A common workaround involves clearing the app cache, which typically resolves the issue within 24 hours. Beyond the reward system, INKR offers a substantial catalog of Asian comics and Western titles, with intuitive categorization by genre and popularity. The reading interface includes both scroll and tap navigation, though some users note accidental screen touches can sometimes disrupt the reading flow. For readers seeking to build their digital collection without financial commitment, INKR's ad-based currency model provides a practical alternative to subscription services or individual chapter purchases.
