Issue a certificate for anything you make. Photograph it, describe it, and hand a living record to whoever owns it next. iCOA is the interactive certificate of authenticity for physical things. Artists, brands, craftspeople and makers use iCOA to issue a certificate for each piece they create: photograph it, describe it, confirm you made it, and issue. The certificate lives on the web at its own address, with a record of who made the item, who holds it now, and every transfer along the way. Buyers can check it in seconds by link or QR code, and the record is anchored on a public blockchain so it outlives any single company, including ours. What you can do in the app - Photograph an item with your camera or pick a professional shot from your library. - Describe it with the fields that fit its category: art, collectibles, memorabilia, fashion, watches and jewelry, furniture and design, instruments, and more. - Issue the certificate and share its public page or printable version. - Transfer a certificate to a buyer by email when the item sells; the new holder claims it with a code, no wallet needed. - See every certificate you have issued or hold, with its full provenance. Who it is for - Independent artists and studios who want provenance that follows the work. - Brands and ateliers issuing certificates at scale. - Collectors who want proof they can pass on with the piece. Plans Free: 3 certificates a month, recorded on chain at first transfer. Credits: buy certificates one at a time or in packs; they never expire. Pro and Studio: monthly subscriptions with higher allowances, recording at issue, custom branding and a printable certificate. Subscriptions renew monthly until cancelled in your App Store account settings at least 24 hours before the period ends. Payment is charged to your Apple account at confirmation of purchase. The maker certifies; iCOA records. iCOA does not appraise or authenticate items on anyone's behalf, and every certificate carries the issuer's own attestation.
