Write a letter, add a photo or your voice, and seal it with wax. Pick a day, and no one can open it until then. Three months, six months, a year, or further into the future — a notification quietly arrives.
Write & Seal
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.
“To someone dear” does not send the letter to them. It stays in your Unletter so you can open it together on the same device.

The Day Comes
Three months, six months, a year, or further into the future — a notification reaches you on the day you chose. Break the seal, open the envelope, and meet your letter again.
A note, always visible before opening, holds the promise — when, where, and with whom to open it.


One of a Kind
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.
Your letters line up in the “Letterbox,” and you can gather your wax seals. A quiet little collection that grows with you.


Safely Kept
Your letters are saved and synced with your own private iCloud database. Unletter also keeps an integrity-checked copy on this device.
If iCloud is temporarily unavailable or its settings change, Unletter does not replace your letters with an empty Letterbox. It leaves the data unchanged and guides you through what to check.

Your letters stay in your private iCloud, with an integrity-checked copy also kept on this device.
Begin gently.
Carry more into the future.
