A Time Capsule Journal

that opens a little every day

A time capsule is a lovely promise: put something small away today, and let a future person, a future you, find it. The trouble with the buried-box kind is the waiting. It opens once, decades out, and most of them are simply forgotten.

A time capsule journal keeps the promise but shrinks the wait. You seal one small line about today, and instead of one far-off opening, it opens a little at a time: what you wrote comes back to you a week later, a month later, and then on this date every year after. “Time capsule” isn’t our word, by the way. It’s the word people who use Little Memory keep arriving at on their own.

The old market street with Maya. Scooters, steam, a hundred small kindnesses.

Slow morning. Pour-over, steam curling in the window light.

Power out all evening. We ate cold noodles by candlelight.

Have it come to you at an hour you pick, or leave notifications off and find them waiting the next time you open the app.

Sealing takes fifteen seconds

Tonight’s contribution, in the iPhone app, is one sentence about today: the soup that finally came out right, the song in the car, the thing you’re quietly hoping for. About fifteen seconds, a photo if you like. A gentle reminder arrives each evening, and one line seals the day. No ceremony, no blank page.

The openings never stop

The first opening comes just a week in, while the habit is still new. Then the month one. Then the anniversaries begin: open the app on any day and there’s this date in every year you’ve kept, and by your fifth year there’s a little stack of yous, sitting together on one screen. People here call the ones that land at exactly the right moment happy coincidences. (There’s a whole page on the on this day side of this.)

That’s what a buried box never gets right: a time capsule is only as good as its opening, and this one opens on the ordinary days too.

A daily time capsule, simple and elegant, a true pleasure to use and remember life’s little memories.

Safekeeping, for a capsule’s whole point is keeping

Little Memory has been holding little time capsules since 2011, with over 1,000,000 memories from over 30,000 journalers, featured by Apple three times. Everything is private by default, backed up nightly to Dropbox if you like, searchable across all your years, and yours to export at any time.

Some people think of each sealed line as a letter to their future self, which is the same idea from the reading end.

If you’re new to keeping a journal this small, the one line a day page covers it, and the little tour is the walkthrough. Building one for a child’s first years is its own version of this, and there’s a page on keeping it as a new parent.

What people say

Very clean and intuitive design. I’ve been using this for 8 months and it never ceases to make me smile everytime an old memory pops up.
James Tamplin, CEO, Firebase
No pushy ads, no up-sells. I love when I see what old memories come up, where I was on the same date years ago.
craisin-chan, App Store review, 2026
It has allowed me to document major life steps in a way nothing else can replicate. This app is far better than the built-in Apple journal.
