About
[ Collect the words. Become yourself. ]
A kind word, a moment that moved your heart,
a phrase you wanted to hold onto—
You felt it so clearly at the time,
but somehow, in the rush of daily life,
it can quietly fade away.
The human brain, it's said,
tends to replay worries and anxieties on repeat.
It's a natural mechanism for self-protection,
but that means warm memories
need to be kept close on purpose,
or they slowly drift out of reach.
At the same time, the brain has another quality:
"What is recalled again and again
sinks in deeper and deeper."
The words you choose, and how often you revisit them,
gradually reshape the texture of your past.
Kokoro Pocket was born from that idea.
◆ What you can do
● Capture a word
A passage from a book, someone's words,
a feeling that came to mind.
Save the moment your heart was moved,
in your own quiet words.
You can add a photo as a memory, too.
● Cherish
For words you want to see often, swipe right.
They're pinned to the top of your pocket
so they're always within reach.
● Put it away
Once a word has settled in your heart,
swipe left to tuck it into your inner pocket.
It doesn't disappear—it quietly becomes
a part of you.
You can bring it back anytime.
● Trace a word
Tap the play button, and the word softly fades.
Trace it in your mind, then tap again
to meet the word once more.
There's no need to force memorization.
This gentle rhythm carries the words
deeper into who you are.
◆ The hope behind Kokoro Pocket
Slip a word that touched your heart into your pocket.
Take it out from time to time, and trace it gently.
May that quiet repetition softly settle the past,
and make today—and the days ahead—
just a little warmer.
That's the hope behind this app.
◆ A space that's yours
Your words are saved only on your device.
Nothing is sent externally without permission,
and no one else can see what you've written.
Feel safe to put your honest feelings into words.
