Hitotsuzuri

Your everyday journal for iPhone

Ordinary days
gently bound
together

A day you remember comes to life again

Revisit the photos and notes you kept
alongside the places you wandered
Little moments become a story of your day

Spend a day with Hitotsuzuri

A home for your everyday memories

A day to rememberSunday
Sunlight falling on a leafy riverside path15:08 The long way home
Coffee and an open book beside a window12:30 My usual window seat
17:42 A passing thought

Nothing special happened
but it was a good day

Illustrative photos and notes

Your days leave little traces

Even the days you never wrote about
leave something to remember

A photo in your library or a few words in a note
Gently brought together in the order they happened
No daily writing habit required — just your own pace

A quiet Sunday out with a book

01 / Keep

Keep a moment
just as you always would

You open your book by the window
Take a photo of the light
Jot down a line you want to remember

Imported photos and the notes you write appear on the same timeline.

The moments before
and after a photo

You take the long way home by the river
Follow your photos and places
and the day begins to unfold again

Bring photos and notes together into a moment and give it a name. Automatic location recording is available when you allow and enable it.

03 / Return

That was a lovely day
Here it is again

One weekend you search your notes for “reading”
That afternoon comes back to you
and you add a thought from today
