About
Coinoscope is a free-to-use, AI-driven coin identification and valuation app available on Android and iOS. By leveraging computer vision technology, the app analyzes a photo of any coin taken directly with a phone camera or uploaded from the gallery and returns a ranked list of matching coins — along with relevant information about their historical context and estimated market value. The app is built for coin collectors, numismatists, and curious hobbyists who want an instant, expert-level answer without visiting a coin shop or spending hours researching online. Its core features include automatic coin recognition, gallery-based uploads, a 'My Collection' manager for organizing saved coins and search results, and a dedicated 'Estimate Value' tool that links out to collector marketplaces for deeper pricing data. Coinoscope also supports a desktop browser mode, allowing users to snap a photo on their phone and review the detailed search results on a larger screen. Since its launch, the app has accumulated over 2.6 million downloads across Android and iOS, with approximately 127,000 monthly active users. The free tier covers all essential features, while the Pro subscription removes ads and unlocks premium capabilities. With support for coins from countries worldwide and a multilingual interface covering 30+ languages, Coinoscope is a truly global tool for anyone passionate about coin collecting.
