Check out my new creation . . . The Comic Locker!

Six weeks ago I started building an app. Not because I planned to but because I kept running into the same problems while combing through back-issue bins at comic stores and comic-cons across Western Canada while researching my upcoming book, The Crisis Companion (coming out this August).

I didn't have a good system for keeping track of what I owned. I didn't know what anything was worth. And I'd get home to file my comics and realize I'd bought duplicates or missed something I'd been hunting for, for months.

So I built The Comic Locker—a comic-collecting app that solves all of these problems and more.

Here are just some of its features:

• Know what you own: Import your entire collection from another app, a spreadsheet, or photos of the covers. Tag where each comic is physically stored—box number, shelf, storage locker—identify gaps in your collection, and create a wish list. Never buy a duplicate again.
• Know what it's worth: Real-time valuation pulled from recent sales and auctions helps you value individual issues and your entire collection. Use it at a con before you hand over cash. Watch your whole collection's value grow over time like an investment.
• AI grading: Get an accurate estimate of each comic's value and condition by taking a photo of the front and back cover, spine, and inside pages.
• Buy and sell without the drama: The marketplace matches buyers and sellers directly—geographically paired, no listing fees, no auctions. Add something to your wish list and get pinged when another user has it for sale and vice versa.
• Get smarter recommendations: The Comic Locker reads your collection and suggests titles, creators, videos, and podcasts tailored to what you actually collect. Own Absolute Batman? Here's a deep dive. Collecting X-Men? Here's a podcast made for you.
• Convention mode: Set a budget, look up prices, log purchases, and connect with other users at the same con using the "I'm Here!" button

The desktop version is live now. Mobile apps for iOS and Android are coming soon. Try it free—no credit card required. If you like it, it's just US$4.99/month or US$39.99/year.
