✨AI Revenue EstimateCONFIDENCE: MEDIUM
The iOS app "Libby, die Bibliotheks-App" itself does not generate direct revenue from end-users, as it is a free service for borrowing digital content from libraries. Sensor Tower data explicitly states that Libby generates no revenue from in-app purchases or subscriptions. The revenue is generated by its parent company, OverDrive, Inc., through a business-to-business (B2B) model where libraries pay licensing fees for digital content. OverDrive's estimated annual revenue is reported to be $420 million.

★★☆☆☆ Terrible e readers
Ok to check out content but does not do a very good job of keeping track of what page you left off on. Annoying to have to keep finding where i was last. A digital bookmark would be a great enhancement…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
