⚡ Quick answer

Missing comics are generated automatically from your owned-issue list: the app cross-references what you've marked as owned against the full catalogue and produces an exhaustive list of what's still needed per series. Bring that list to a con, upload it to eBay saved searches, or share it with dealers.

Why running incomplete runs costs money

A collector working on a long run without a precise missing-issues list ends up doing two bad things: buying duplicates (because they forgot they already had #47), and paying premium prices at conventions for issues they could have picked up for half on eBay. Both problems disappear when the missing-issues list is live, accurate and in your pocket.

Automatic missing-issue detection

Import your series, check what you own, and the app produces the inverse list: every issue in the series you don't have. Sort by issue number, filter by key-issue status, export as a CSV wantlist.

At the convention, you pull up your list on your phone. Scan any comic that catches your eye — if it's on the wantlist, green light. If not, red. No guesswork, no duplicates.
