Write the letter now. They open it when they need you most.
Seal a letter for your partner that only unlocks when its moment comes — a hard day, a random Tuesday, the anniversary you never miss.
They’ll see it waiting in their pocket — sealed, impossible to peek. And the moment they break the seal, you’ll know.

Three steps, one seal.
- first
Write & seal
Pour it out while you feel it — a pep talk, an apology in advance, a love letter for a random Tuesday. One tap seals it shut.
- then
It waits, sealed
The letter sits in your partner's pocket, locked. They can see it's there — they just can't open it until the moment you chose.
- one day
They open it when the moment comes
The hard day arrives, or the anniversary does. They break the seal, read your words — and you get a quiet ping that they did.
Sealed means sealed. Your partner can’t peek.
