Unsent
You've taken so many photos of your kids.
But how you felt that day is nowhere to be found.
Just speak to your phone, and add a few words to the moment.
It becomes a diary — and later, it comes back to you.
You take the photo, but the feeling of that day fades. Just talk to your phone and the AI shapes your words into a diary. However busy you are, it only takes a few words to add how you felt.
Up to 10 photos and video per entry — not just words, but their face and voice that day.

Just like the “a year ago today” from your photo app — but here it's your diary. Entries from a week, a month, a year ago quietly return on LINE. This time, not just the photo, but how you felt that day.
You can adjust how often these reminders arrive.

When a past entry returns, the same day is quietly shared with the person you choose. Even apart, you revisit your child's growth together.

As your entries grow, the AI reads the shifts and patterns in how you feel — helping you notice your own heart amid the parenting days.

Other apps resurface your child's “a year ago today.” But all they bring back is the picture. Unsent brings back what you felt that day, too.
