About

Vellum

Read full description

Vellum is a time-gift app where you send audio and video capsules to the future. Record today, open years later. To yourself, or to those you love. CAPSULES FOR THE FUTURE In Vellum, every capsule is a sealed envelope. You set the opening date: a year, ten years, twenty-five years from now. Until the date you choose, the capsule stays closed even you cannot listen to it. The seal cannot be broken before its time, because the essence of Vellum lies in the waiting of the word you sent to the future, and in its remembrance when the moment arrives. SEND A GIFT TO YOUR LOVED ONES You can send Vellum capsules to someone else too. A message for their birthday, a congratulation for their graduation, a word for your child's eighteenth. Even if the other person doesn't use Vellum, they reach the capsule through a link and add it to their own iCloud account. That capsule is now theirs even if you delete Vellum. YOUR CAPSULES, YOUR iCloud Vellum has no server. All your capsules are kept in your Apple iCloud account, encrypted end to end. We can never access their contents. When you send a gift, the capsule reaches the recipient directly through iCloud there is no server between us. BUILT TO LAST We built Vellum on Apple's infrastructure because we want it to still be working ten years from now. Companies close, servers shut down, apps disappear. Your iCloud account, though, stays yours. Vellum is just an interface that uses that trust. WHAT YOU CAN DO - Record an audio capsule (in your own voice, in your own words) - Film a video capsule - Choose the opening date: 1 month, 1 year, 25 years from now - Add a personal note - Send to yourself or to someone close - Track the status of the capsules you've sent WHO USES VELLUM - Those who leave a message through time for their loved ones on birthdays - Parents who record their child's growth day by day and prepare capsules to be opened at certain ages - Those who want to give themselves a word on anniversaries, on new beginnings - Those who do not want to lose their memories Vellum was made for thinking about permanence. It is not a fast tool it is a slow ritual.

Some pairs you know cold. The fifteenth pair, and the box in the back, you don't. Point the camera at the shoe and the model, colorway, and year land in the archive next to it. What you get: • Point-and-identify: model, colorway, and release year from the shoe itself • Construction and colorway detail for checking a pair against the reference • A full collection archive, every pair in one place, edits stand • Acquisition date and condition logged on each entry • Release story and run notes saved next to the pair, not lost to time • Per-pair archive entry that stays open for your own notes Free and Premium: Soledex is free to download, with three identifications and three Assess runs included every day. Unlimited identification, unlimited Assess, the full reference catalog, exporting, and unlimited reminders require a Soledex Premium subscription (auto-renewable, priced in the app before purchase). How it feels: Rico works one detail at a time. The crease across the toe box, the yellowed gum sole, the tag inside the tongue. One observation per pair, grounded in the shoe in front of him. He'll name the year when it earns the line, and stay quiet when it doesn't. Who it's for: • The collector who owns enough pairs that the shelf outpaced the memory • The buyer who came home with a colorway already sitting three boxes deep • The keeper who wants the release details ready when someone asks Privacy: Your archive lives on your device. Photos and notes stay in your collection, not a public feed. See the privacy policy for the full picture. Worth pulling the box for.
