what's inside

Four small things, kept well

Letters to your future self

Write it now, pick the day it opens. Until then it's sealed: not even you can read it early. You can only push the date later.

Countdowns to anything

Exams with a target score, birthdays, weddings, trips, deadlines. Show the time left in years, months, days or hours: whatever feels right.

A calendar in pictures

Add a photo, or a short video, to each day. Pin one as the day's wallpaper. The month fills up as you go.

Memories you can wander

Every day you kept becomes an island on a board you can pan and zoom, newest in the middle. A whole year, at a glance.

and a buddy that's yours

Make your own character

Pick a color, eyes, a smile, ears or horns, a little accessory and a background. It lives in your menu and keeps you company.

Psst. What you write
stays between us. Well, just you.

private by design

Yours, and only yours

  • Letters are end-to-end encrypted

    They're locked on your device with a passphrase only you know, before they're saved. Nobody else can read them, including us.

  • Sealed means sealed

    The unlock date is checked by the database's own clock, so changing your phone's time won't open a letter early.

  • Your pictures stay private

    Photos and videos sit in your own private folder, behind links that expire. Nothing is public.

  • Leave anytime

    Delete your account and everything in it, for good, from one button. No email to send, no waiting.
