About Unletter
Unletter lets you seal today's feelings into a "special envelope" and deliver them to the future. ■ Write a letter and seal it Add photos or your voice to your message, then seal the envelope with wax. Once you pick an open day, no one can see inside until that day arrives. ■ A note you can see before opening Keep the contents hidden, but leave a short note about the promise — when, where, with whom, and on what occasion to open it. The note is always visible before opening, a gentle reminder of the day to come. ■ A one-of-a-kind wax seal Every time you seal a letter, a wax seal is born that is never the same twice in color or shape. A special seal for your letter alone. ■ When the day comes One year, five years, ten years later — a notification arrives on the day you chose. Break the seal, open the envelope, and meet your letter again in the future. ■ Collect them in your Letterbox Your letters line up in the "Letterbox." Browse the shelf of envelopes, or gather your one-of-a-kind wax seals in the "Seal Collection" — a quiet little collection that grows with you. ■ For moments like these - To your future self: today's dreams and worries - To someone dear: words for an anniversary - For milestones: coming of age, graduation, a wedding ■ Leave your voice (Pro) Some feelings words can't carry — say them out loud. Hearing your own voice, or a loved one's, in the future is a gift like no other. ■ Kept safe, always Your letters are stored safely in your iCloud and synced across devices signed in with the same Apple ID. Even when you change phones, your letters to the future carry over. Your data stays in your private space and is never sent or shared with third parties. Today's heart, sent to the future.
