MetaX is a free multimedia metadata editor available for iPhone users. With MetaX, users can conveniently check and edit main metadata such as ISO, Shutter Speed, Aperture, FNumber, and more. Additionally, the app allows users to add dates and locations to images, as well as remove all metadata if needed.

Moreover, MetaX supports HEIF format, enabling users to work with high-quality images efficiently. Users can download images directly from iCloud and organize them in the dedicated "MetaX" album. The app offers two save modes, giving users the option to delete the original image simultaneously or retain it. Compatible with both iPhone and iPad in horizontal and vertical orientations, MetaX provides a user-friendly solution for managing image metadata on iOS devices.
