hibiA journal for the days
you’ll look back on.

One line, just for you.

hibi is a journal app for keeping what happens each day and how you feel, starting with just a few words.

The journal list. Cards with photos are lined up by date.

No one else sees it,
so you can write anything.

Your journal stays on your device.

    Your journal is saved on your device. The people behind hibi have no way to access it.

    Backups go to your own Google Drive, a place you control. The people behind hibi can’t see it.

  3. 03

    There’s no advertising ID, and no third-party tracking.

On This Day

Words from that day, arriving today.

Open On This Day, and your entries from 1 week, 1 month, 6 months, and 1 year ago line up for you today. You can start looking back the week after you write.

The On This Day screen. Past entries from the same date are lined up, newest first.
Quote

Pick up where that day left off.

Quote a past entry and continue it in today’s entry. The words from that day and the words from today stay connected.

Cards

A few words become a picture.

A line of up to 140 characters. Each entry turns into a different card on its own, depending on how long it is and whether it has photos, so each day keeps its own feeling, in its own card.

Gallery

Your days become a pattern.

Switch Home to Gallery, and the photos from your entries line up as tiles. You can look back over your days through photos, not words.

Monthly Report

Look back on your last month.

When a month ends, look back on its entries with a cover and highlights. Your Monthly Reports line up on the bookshelf, so you can read them again anytime.

Why we made hibi.

Social media is a place made to be seen by someone.
There wasn’t a journal where you could easily write even what you’d never put on social media, and where no one else would see it.
So we made hibi.

hibi cares about looking back on your journal as much as writing it.
What were you writing on this day a year ago?
Each time you look back, you’ll see what has changed, and what hasn’t.
