WhatChanged – Folder Compare
Compare files & folders safely
$9.99
Compare files or folders on iPhone and iPad. Spot edits, renames, and content differences with optional SHA-256 — all read-only.
WhatChanged helps you answer one question fast: what’s different?
Compare two files or two folders and get a clear, read-only summary of changes on iPhone and iPad.
Perfect for backups, exports, cloud drives, builds, and any “did this copy match?” moment.
◼ How to use
• In the app
Open WhatChanged
Choose two files or two folders (Left and Right)
Tap Compare
• From the share sheet
In the Files app (or another app that can share files), select exactly two files
Tap Share → WhatChanged
The report opens in WhatChanged automatically
Tip:
The extension is best for file-to-file compare. To compare folders, open the main app.
◼ Highlights
• Compare files and folders (left vs right)
• Folder compare with rename detection
• Built‑in text diff for supported text files, with unified and split views
• Optional SHA-256 verification for content-level certainty (with caching for faster re-checks)
• Smart ignore rules: hidden items, extensions, names, and patterns
• Text-friendly options: ignore line endings and whitespace-only changes
• Preview supported files, keep recent comparisons, and export/share reports
• 25 languages, plus an optional in-app language override
◼ Safe by design
WhatChanged doesn’t modify or delete your originals. Comparisons stay read-only on your device.
Requires iOS 16.6 or later.
