Seal it and mean it.
Once the wax is on you can't rewrite it. That's the whole point.
The slow way to say something.
Sealed letters that open in time.
Write it today. Choose the day it opens. It sits on their home screen counting down — until the wax breaks and the words are finally theirs.

How it works
Write it.
Pick the date.
Seal it.
Three steps, then patience
Words, a photo, the small detail you'd forget by next winter. Tomorrow morning. Their birthday. This time next year. Pick a wax, a colour, a stamp. Press it shut and it stays shut.

Seals, fonts, colours for every moment.
The picture from the day you're writing about, sealed in with the words. Seals, fonts, colours and stamps for every kind of occasion.

Until they break the seal…
And when it opens
You'll know the moment it opens.
You'll see when it's delivered, and when they open it. And the moment they do, they can react — one tap, straight back to you.

Questions
The things people ask.
01Can I edit a letter after I seal it?
No — that's the whole point. Once a letter is sealed and sent, you can't rewrite it, and you can't call it back — not you, not us. Same as dropping it in a postbox: once it's in the mailman's bag, it's gone to meet its day.
02What if they don't have the app yet?
Send them a link. The sealed letter waits until they install Willovit and pair with you; nothing opens early and nothing gets lost.
03How far ahead can I schedule?
An hour from now to years out. Pick a date and a time of day — the letter opens on the minute, in their timezone.
04Can one letter go to several people?
One letter, one person, one day. Write as many as you like, but each one is addressed to a single reader.
05Do you read the letters?
We can't. Everything is encrypted on your iPhone before it leaves, and the keys never touch our servers. All we see is an unreadable blob and a date.
06Is there anything to keep up with?
Nothing. No streaks, no likes, nothing to scroll. There's an inbox of letters, a calendar of days, and a widget that counts down. That's the whole app.
For secrets, love letters, anniversaries…
Write one tonight. Let it wait.
Free to use. One letter is enough to see why the waiting is the gift.
It'll be there on the day.
