A box you pack, and actually seal.

Notes, photos, a voice note, a song, a promise, a question. Opened whenever — or not before a day you pick, or one a day until it's empty.

Make one

No account. Nothing to install. Takes about ten minutes.

Up to twelve things, and only one of them opens today.

How it works

Pack it

Up to twelve goodies, in any order. Write on the outside of each one — open when it's a bad day — or leave it a surprise.
Seal it

Open whenever, or not before a day you pick, or one a day — counted from when they first reach for it, so a box opened late still lasts.
Send the link

No app, no account. When the last one is open, they get what you wrote at the end.

The seal is real: Everywhere else puts the whole box in the page and draws a lid over it, so anyone curious can read tomorrow's today. Here each goodie stays on our server until it is opened.
Nothing loads until it's opened: A song or a video plays right there — Spotify's player, YouTube's — but only once that goodie is open. Nothing is fetched for one they never open. YouTube comes from its no-cookie host, and the share tag that identifies you is stripped off the link.
It doesn't expire: No “kept for at least twelve months”. It stays until you delete it, and the link that does that works from any device.
They can answer back: Put a question in the box and whatever they write comes back to you. One goodie can also be locked behind a word only they would know.
