SpacerMint runs entirely on-device. No cloud uploads, no user accounts, no third-party analytics. Scan history lives in a local SQLite database and disappears when you delete the app.
It finds duplicates using visual fingerprinting combined with metadata (file size, dimensions, GPS, timestamps), detects similar/burst photos, cleans up old screenshots, compresses video with adjustable quality tiers, and surfaces bloat from WhatsApp/Telegram/iMessage media.
Free on the App Store. Would love feedback on the detection accuracy and anything you'd want added.
