TwinClean

An Android duplicate-file cleaner that finds exact copies across photos, videos, audio and documents, grouping every match so you can review before cleaning. Matches are verified with a full SHA-256 checksum over the whole file — identical content is the only thing that matches, never "similar looking" — and Smart Select keeps the newest, best copy by default. Cleaning moves files to an in-app Trash that stays restorable for 30 days (single file, whole group, or everything), never deleting originals outright. No cloud, no account, no analytics.

Highlights

• SHA-256-verified exact matching in a background isolate — never fuzzy
• Smart Select auto-keeps the best copy; each group shows its match evidence
• 30-day recoverable Trash with single-file, whole-group, or full restore
