Blind Box Shelf is an offline collection manager for blind box collectors. It helps you record owned items, duplicates, wish list picks, box-opening costs, and display shelf locations. Create collection files by series, mark regular items, secret items, missing items, and duplicates, then review full-set progress and spending stats. The app requires no account, does not connect to the internet, and does not collect personal data. All records stay only on your device, making it suitable for long-term collection tracking.
