Aves Libre

Aves Libre, published by Thibault Deckers, is an Android gallery application that doubles as a metadata explorer. Alongside browsing the photos and videos held on the device, it surfaces the descriptive data attached to those files, which is the part most gallery apps keep out of sight. That makes it relevant if you care about what a file records about itself, not only how it looks in a grid.

The metadata angle suits work such as sorting through a camera import, checking what information travels with an image before it leaves the device, or inspecting files whose origin is unclear. The project is released under the BSD-3-Clause license, a permissive license that requires attribution and prohibits use of contributor names for endorsement. Availability is limited to Android; no desktop or iOS version is listed. Which specific metadata standards and file formats are handled is not covered by the facts available here and should be checked against the project's documentation.
