Hibiwa: Notes for Loved Ones

One card a day. To one close person.
No notifications every minute. No likes. No algorithm.

Hibiwa is a quiet space for one daily gesture — between two close people. A couple. A mother and son. A grandmother and grandchild. A sibling. Your closest friend.

WHAT HIBIWA IS
Hibiwa (日々和 — "daily harmony") is an app for leaving exactly one card a day to exactly one close person. Not chat. Not social. Not a streak. Not a journal for yourself — unless you want it to be; there's a "for yourself" mode too. Just a short daily gesture — two sentences, one memory, one warm touch — kept forever in your shared keepsake box.

WHY ONE
Because the daily measure forces presence. You don't write whenever — you write when you actually have something to say. The same thought that could scatter into twenty messages distills into a single sentence. It's the difference between a letter and a text.

HOW IT WORKS
• No sign-up — Hibiwa uses your iCloud account. No password, no email.
• Send your loved one an iMessage invite link.
• Leave one short card a day. The limit resets at dawn (5:00 local time).
• They see your card under a soft mist — a long press reveals it.
• Warm trace — a double tap sends a gentle haptic to their phone. No words.
• Together now — a soft dot lights up when you're both in the app at the same moment.
• Sealed envelope — a card for a hard day, for when they miss you. Opened only when they choose.
• Keepsake box — every card kept, like a real lacquered chest.
• Apple Watch — glance at the latest card on your wrist; feel a warm glow when your person reaches out.

24 SEASONS
Hibiwa breathes to the rhythm of the 24 Japanese microseasons (sekki). Every two weeks the accent, the prompt, and the color shift. Spring's awakening, summer's solstice, autumn's clearing — the app changes with the season you're living in.

QUIET AND PRIVATE
• No servers of ours. Your cards travel through your own Apple iCloud — Hibiwa has no access to them.
• No trackers. No ads. No third-party analytics.
• Privacy Manifest compliant.
• Your relationship is yours. Our work is to protect it.

WHO IT'S FOR
For long-term couples who want to tend daily intimacy without messaging-app overwhelm. For a mother and a son in another city. For a grandmother and a grandchild who want to leave something that outlasts the years. For siblings scattered across the world. For your closest friend. And for yourself — a "for yourself" mode lets you write to your future self.

Not for everyone. Not for every day. For the days when you want to say, "I remember you."
