Volumes is a reading companion for thoughtful readers. Track the books you read, rate them, and reflect on what stayed with you. Over time you'll build a personal library that becomes richer with every entry.

Every recommendation includes a short note explaining the connection, helping you discover books that genuinely fit your taste. Bring your reading list with you — Already keep a list in Notes, a spreadsheet, or somewhere else? Paste it in and Volumes will magically import it, matching each title with cover art and preserving your ratings and notes. Your library starts full, not empty.

Verdict
The clearest difference is update cadence: Volumes at every 5 days against Curio Library's every 21 months. Curio Library's advantage is monetization model (free vs ad-supported) and iOS requirement (11.1 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
