Manga Shelf Ledger2026 app analytics for August 24

Manga Shelf Ledger is an offline tool designed for manga volume collecting, gap tracking, and shelf organization. It is made for readers who buy manga regularly, follow long-running series, organize bookcases, track first-print bonuses, or record secondhand condition. You can create a record for each series and track every volume's owned status, edition, condition, purchase price, shelf location, and lending or return status, helping you avoid duplicate purchases and missed volumes. Core features: 1. Series volume management: set total volumes, owned volumes, missing-volume lists, and completion status. 2. Edition and condition notes: record first prints, reprints, special editions, bonuses, obi bands, and book condition grades. 3. Restock list: automatically summarize unowned volumes for checking at bookstores, conventions, and secondhand marketplaces. 4. Shelf location: record cabinet, shelf level, box number, and physical book position. 5. Lending and returns: track borrower, lending date, and return status. 6. Spending statistics: calculate purchase amount, average price, and collection cost by series. All data is stored only on your device.
