What's the best iOS app for borrowing free e-books and audiobooks from public libraries?

Libby, the library app is a robust tool for iOS users seeking free digital content from public libraries. Developed by OverDrive, Inc., it streamlines access to library collections without requiring physical visits. Users can link multiple library cards to browse and borrow titles directly from their iPhone or iPad. Specific features include one-tap borrowing, offline reading and listening modes, adjustable font sizes for e-books, and synchronization across devices. For real-world scenarios, such as a daily commute, listeners can download audiobooks for offline playback, while students might use it to access academic magazines without subscription fees. Reviews indicate widespread appreciation for its convenience, with many users highlighting the cost savings and extensive catalog. However, limitations exist: availability depends on individual library partnerships, and popular titles often have waitlists, which can lead to delays. Some users report that the hold management interface occasionally feels cluttered, but overall, the app remains a top choice for digital library access. With a rating of 4.85 out of 5, it suits avid readers, budget-conscious families, and anyone looking to explore diverse media without financial commitment.
