Duren`

Duren is a hands-on authentication board for fans who verify overseas luxury buys.
Instead of scrolling tips, you build the case: add checkpoint photos, stamp each
verdict, and keep a running confidence score on one board.
WHAT YOU CAN DO
• Create boards for handbags, sneakers, watches, and other categories.
• Capture close-ups or import purchase photos as authentication checkpoints.
• Stamp Authentic, Suspect, or Off on each checkpoint with captions.
• Record a spoken note on any stamp to explain what you saw.
• Watch Verdict Tally update a live confidence score as you stamp.
• Browse the offline Hallmark Index and pull standard checkpoints into your board.
• Review saved boards, remove checkpoints, or delete a board when you are done.
• Export your board canvas as an image and save it to Photos.
PRIVATE AND OFFLINE
