IMb Scanner App is a free utility tool available on iPhone that utilizes the device's camera to scan and convert USPS Intelligent Mail Barcodes (IMb). These barcodes, commonly found on mailpieces, assist the USPS in efficient mail delivery. The app decodes the barcode information and presents users with a straightforward text breakdown of the IMb.

Currently, the app exclusively supports scanning and decoding USPS Intelligent Mail Barcodes (IMb) and does not extend its functionality to other types like POSTNET barcodes. Users are encouraged to keep the app updated to access potential new features such as expanded barcode scanning capabilities and conversions.
