BacknumberSpot missing issues instantly

Backnumber is a fast, fully offline tracker built for people who collect single comic book issues — not trade paperbacks, not digital bundles, just the individual issues in your longbox. Add what you own, see exactly which issues are missing from every series, and keep a want list for the ones you're still hunting down.

Every other comic app wants your Wi-Fi and your email address. Backnumber doesn't. There's no account, no cloud sync, and no ads — your whole collection lives in a single file on your device that you can back up or hand off whenever you want.

WHAT MAKES BACKNUMBER DIFFERENT

• Log every issue: series, issue number, publisher, variant, condition, and price paid
• See series completion at a glance — Backnumber shows exactly which issue numbers you’re missing from any run
• Keep a separate want list and move items to your library the moment you track them down
• Mark issues unread, reading, or read to keep your to-read pile organized
• Scan a barcode to speed up entry, or type it in by hand
• Back up your whole collection to a JSON file, or export a CSV for spreadsheets and insurance records
