Collect words. Shape who you are.
A moment of joy. A line that moved you. Words you wanted to hold on to —
You felt them so clearly at the time, yet somewhere in the rush of daily life, they quietly fade.
It's said that our minds are inclined to turn worries over and over. It's a natural way of protecting ourselves — but perhaps, because of it, our warmer memories slip quietly away unless we give them our attention.
At the same time, it's also said that the more often we recall something, the more deeply it settles within us.
Which words you choose, and how often you return to them, can gently change the texture of your own past. Kokoro Pocket was born from this idea.
◆ What you can do
• Write down words
A passage from a book, words from someone dear, a feeling that suddenly surfaces. Gently set down the moment that moved you, in words that are yours alone. You can add a cherished photo, too.
• Keep them close
Swipe right on the words you want to see again and again. They're pinned to the top of the screen, always within reach.
• Tuck them into the inner pocket
Once a word has settled deeply within you, swipe left to tuck it into the inner pocket. It isn't gone — it quietly gathers as a part of you. You can bring it back anytime.
• Trace the words
Tap the play button, and the words softly disappear. Trace them gently in your mind, then tap once more to meet them again. There's no need to force yourself to memorize. This quiet rhythm of repetition carries the words deep within you.
◆ What Kokoro Pocket hopes for
Tuck the words that resonate into your pocket, and now and then, take them out and trace them.
We hope that this quiet repetition gently reshapes the past, and makes today — and the days to come — just a little warmer.
It was with that wish that we made this app.
◆ About ads
Every feature of Kokoro Pocket is free to use. To help keep it running, the app shows ads.
For those who'd prefer a quiet, ad-free screen, we offer a one-time purchase that removes them. Nothing is restricted — only the presence of ads changes.
◆ Your own quiet place
The words and photos you keep here
stay on your device.
They are never sent to any server,
and never seen by anyone else.
An in-app purchase briefly connects
your device to Apple to complete the payment —
but the words and photos you keep here
are never sent along with it.
Write freely, and with peace of mind.
