## What is dfirOS?

dfirOS Viewer is a focused evidence browser for iPhone and iPad.

OPEN EVIDENCE IN PLACE
• Select E01, AFF, AFF4 or raw/dd images from Files or external storage
• Open split evidence by selecting its segments or granting access to its folder
• Evidence stays on your device and is not uploaded

BROWSE WITHOUT BUILDING AN INDEX
• Enter supported file systems and browse folders on demand
• Open individual files without importing the entire image
• View file metadata and read file content in pages

EXAMINE INDIVIDUAL FILES
• Preview images, text, PDF, plist, SQLite, Office documents and EXIF metadata
• Calculate a hash for a selected file

The iPhone and iPad app is deliberately a viewer. Case wide search, artifact scanning, triage, timelines, reports, AI and OCR remain in dfirOS for Mac.

An active dfirOS subscription grants access through universal purchase.
