About
Stamp Identifier App is a specialist AI tool built for philatelists and casual stamp collectors alike. By pointing an iPhone or iPad camera at any stamp, users receive near-instant results that include the country of origin, year of issue, Scott catalog number, estimated market value, and rich historical context—all powered by a cloud-based AI model trained on millions of stamp images. Value estimates are derived from recent auction results, catalog references, and current collector market trends, and are updated regularly to stay accurate. Even partially damaged or worn stamps can often be identified, with the app flagging lower-confidence matches so collectors can compare details manually. Beyond identification, the app doubles as a digital collection manager, letting users save, organize, and review every stamp they scan with its full data record. Previously identified stamps and their details remain accessible offline, making it useful at flea markets, estate sales, or stamp fairs where connectivity may be limited. With more than 3,000 daily scans and a 4.5/5 user rating, Stamp Identifier App is aimed at hobbyists building or appraising collections, estate handlers valuing inherited stamps, and serious philatelists seeking quick catalog lookups. An Android version is planned for future release. New users receive complimentary scans to try the service before committing to a paid plan.

Frequently Asked Questions
How accurate is the Stamp Identifier App?
The app achieves over 95% accuracy on common stamps. For rare or unusual stamps it provides the closest matches and confidence indicators so you can compare details manually.

Yes. The app can often identify damaged or incomplete stamps, though accuracy may be lower. It will flag reduced-confidence results so you can manually review the closest matches.
