StampSnap: Stamp Identifier is a free iPhone app developed by Hoang Nguyen. Designed for stamp collectors and enthusiasts, this app utilizes advanced image recognition technology to identify stamps and provide users with more information about them. The app sources its stamp details from Colnect.com, the world's largest online stamp catalog and social network for collectors.

With StampSnap, users can simply take a photo of a stamp and the app will automatically detect and crop the image to focus on the stamp itself. The advanced image recognition technology then analyzes the stamp and matches it with the corresponding entry in Colnect's extensive stamp catalog. Users can access detailed information about the stamp, including its design, country of origin, and other relevant details.

StampSnap also offers additional features such as the ability to save favorite stamps for later review. Users can capture images of stamps using the app's built-in camera, select photos from their gallery, or even share images from other apps for identification.

Please note that StampSnap: Stamp Identifier is available for iPhone users and is free to download and use. For more information about the app's terms of use and privacy policy, please visit the developer's website provided.
