Find duplicate photos, choose the shots to keep, and reclaim storage without uploading your library. PicDeDupe analyzes photos privately on your device and keeps you in control before anything is removed. SMART DUPLICATE CLEANUP • Find duplicate and visually similar still photos. • Apple Vision verifies scan results on device for both Free and Pro. • Review recommended keepers using sharpness, exposure, visual quality, resolution, favorites, and your preferences. • Change the keeper before cleanup. • Choose Strict, Normal, or Loose matching sensitivity. • Videos, bursts, and Live Photos have separate cleanup screens. MORE WAYS TO RECLAIM SPACE • Review large videos sorted by size. • Review screenshots and burst sequences in focused cleanup screens. • Burst recommendations prioritize your picks and favorites, then assessed image quality. • Identify likely blurry photos among your most recent 300 photos. • Review Live Photos, with a clear reminder that deleting one removes both its still image and motion clip. • Track estimated storage savings and cleanup progress in Insights. PRIVATE BY DESIGN Duplicate comparison, Apple Vision verification, and keeper analysis run on your device. Your photos are not uploaded. No account is required, and the app contains no ads or third-party tracking SDKs. Cleanup summaries report the scan's counts and estimated savings. REVIEW BEFORE REMOVING You review the selected items before deletion, and Photos asks for confirmation. Deleted items move to Recently Deleted. With iCloud Photos enabled, deletion also syncs to iCloud and your other devices. Storage estimates can differ from space immediately available on your device. FREE AND PRO Free includes one successful duplicate scan per day with the same Apple Vision verification as Pro, access to the three highest-value duplicate sets, and manual review. A scan with no duplicate groups does not use your daily allowance. PicDeDupe Pro adds: • Unlimited scans and every duplicate set • Smart Clean and bulk review • Advanced keeper preferences and explanations • More frequent background checks • Blurry and Live Photo cleanup • Keeper recommendation export Pro is available through Weekly and Yearly auto-renewable subscriptions or a one-time Lifetime purchase. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel them in your Apple Account subscription settings.
