Unletter lets you seal today’s feelings in a special envelope and open them in the future. ■ Write a letter and seal it Add photos or your voice to your message, then seal the envelope with wax. Once you choose a day to open it, the contents stay hidden until that day arrives. ■ A note you can see before opening Keep the contents hidden while leaving a short note about the promise—when, where, with whom, and on what occasion to open it. You can revisit the note any time while you wait. ■ A one-of-a-kind wax seal Each time you seal a letter, a wax seal is created with a unique color and shape. It becomes a special seal for your letter alone. ■ When the day comes Three months, six months, a year, or further into the future—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 your shelf of envelopes or collect each unique wax seal in the Seal Collection. Your own collection grows with every letter. ■ A letter for someone dear “To someone dear” does not send the letter to another device. It stays in your Unletter so you can open it together, on the same device, on the day you choose. ■ For moments like these • Share today’s dreams and worries with your future self • Save words for an anniversary to open with someone dear • Mark a milestone such as coming of age, graduation, or a wedding ■ Leave your voice (Pro) When words aren’t enough, leave up to 3 minutes of your voice. Hearing your own voice—or the voice of someone dear—in the future can become a gift unlike any other. ■ Saved here, with optional iCloud sync Letters you create, or download and save from iCloud, are kept on this device with an integrity-checked copy. Saved letters work offline and stay here when you turn sync off. When updating from V1, Unletter automatically recovers iCloud letters, respecting earlier off settings. Letters not yet downloaded need access to the Apple Account’s iCloud where they were saved, then download and on-device saving. Initial recovery only receives letters. Turn on sync in Settings to automatically sync all existing and new letters both ways with your iCloud. The developer cannot access your letters’ contents. ■ Deleting a letter Deleting removes the letter and attachments from this device. When sync is on and connected, deletion also reaches the same Apple Account’s iCloud and syncing V1.1 devices. Offline deletions are recorded here and applied when sync is on and connected again. Today’s heart, kept for the future.
