Lacuna: Time Capsule

Seal a letter, a photo, or your voice — then lock it until a date you choose. No peeking. No extending. The waiting is the point.

Leave something for the person you'll become. Lacuna is a time capsule for your future self — seal a letter, a photo, or a voice note, and lock it until a date you choose.

When the time comes — days, months, or years from now — it opens. Not a second before. No peeking. No extending. That is the point.

And when it opens, it opens with ceremony — a moment made to be felt, not a notification you swipe away.

— What You Can Seal —

• Text — Write a letter to your future self, to someone you love, or to someone who doesn't exist yet. Real formatting: bold, italic, paragraphs. A letter, not a text message. Not sure where to start? Reflective writing prompts help you find the words. • Photos — From your library or camera, preserved exactly as they are today. • Voice — Capture what writing can't: tone, laughter, the pauses. The things you forget first.

— A Letter to Tomorrow —

Open Lacuna, answer a prompt, and seal a thought for tomorrow-you in under a minute. A quiet daily ritual — a note from who you are today to who you'll be next.

— Send It to Someone —

Seal a capsule and send it straight in iMessage. They tap once and it opens in Lacuna when the date arrives — no files, no fuss. Or share it any way you like: AirDrop, WhatsApp, email. Photos and voice are end-to-end encrypted in transit, so no one can peek — not even you. A gift wrapped in time.

— Why Lacuna —

Most apps fight for your attention right now. Lacuna does the opposite. It asks you to put something away, and to trust that the waiting is the point. No feeds. No followers. No algorithms. No accounts. Everything stays on your device and in your private iCloud. Your memories belong to you, and only you.
