ViewExif is a powerful metadata tool for photos, offering features such as displaying EXIF tags, including dimensions, taken date, ISO speed, and focal length, as well as IPTC tags like star ratings, keywords, and descriptions.

With support for various image formats, including JPG, PNG, TIFF, HEIC, and RAW formats like CR2, NEF, and DNG, ViewExif is a versatile tool for photographers and individuals concerned about privacy. The app's technical implementation includes an app extension for the Photos app and third-party apps, allowing for seamless integration and use. Specific use cases for ViewExif include protecting privacy by removing personal information like geo location and taken date before sharing photos, and utilizing the app's features to analyze and understand the settings and tools used to create a particular photograph. As a unique differentiator, ViewExif's ability to display geo location on a map and remove metadata before sharing sets it apart from other metadata tools.
