Mom keeps a moment
Grandma sees it right away
Tiny moments, kept forever.
What is Cubi?
A private baby diary, not another social network
Cubi helps parents keep photos, videos and a few words from the days their child grows, organized by the child's age and shared only with invited family. New photos can appear automatically on the whole family's home-screen widgets, so far-away grandparents see the little one each day without digging through group chats.

Made for the whole journey
More than a photo album
Cubi brings the scattered parts of family memory-keeping into one quiet place: journaling, photos and video, growth, family sharing and keepsake films.
A diary that grows with the baby
Each photo, each short video, each line you write becomes a page in the baby's diary. Keep the first laugh, the first roll, the first word — and over time those pages become a whole story of the early days the family can open again.
The baby on the home screen, all day
The home-screen widget shows the baby's latest photo and the baby's age, quietly changing through the day. Open your phone and the baby is there; grandparents far away open theirs and the little one is there too — on both iPhone and Android.
Invite the whole family with one code
Share a code or a link, and grandparents, aunts, and uncles just open it to watch the baby grow. No account, no password, nothing complicated — even the family who finds phones fiddly can come in gently.
A heart, instead of a reply
The family taps a single emoji when the baby melts their heart — that's all. There are no comments, no pressure to reply. One heart from grandma is sometimes warm enough for the whole day.
The baby belongs to the family alone
No public feed, no strangers, no followers, no ads. You choose who sees each moment of the baby. This is a quiet, private corner just for the people who truly love the little one.
The baby's age appears on its own
Six months and twelve days old — Cubi works out the baby's age and shows it on its own, so you never have to count. Each moment sits along a gentle timeline, so the family can see the little one growing bit by bit.
Memories become a little film
Pick 5–30 diary photos and a style. Cubi turns them into a keepsake video with music to save or share with the family.
One family, every little one
Follow more than one child in one calm timeline. Each invitation can open exactly one or several children's diaries for family.
Follow every growing step
Keep height, weight and the things your child loves beside their photos, videos and age milestones.

Why Cubi exists
A quiet space, not a feed
Cubi was made for days when the baby grows too fast, and for the people who love the little one from too far away. There are no likes to chase, no comments to answer — just one small heart sent to the baby. Cubi steps back quietly, so the family feels close and private, never watched. What is left is simply the baby, and the people who love them.
Each moment can be for Everyone, Selected people, or Only me. Parents always decide.
The baby belongs to the family alone
- No public feed, no strangers, no followers.
- No ads in the baby's moments.
- You choose who sees each of the baby's moments.
- The baby belongs only to the people who truly love them.
- Made in Vietnam, for Vietnamese families.

For parents
Young parents who want to keep every day of the baby growing up somewhere warm and private — instead of letting the baby's photos drift away in noisy feeds.
For grandparents and family
Grandparents, aunts, and uncles far away, longing for each photo of the little one. They open Cubi and there the baby is, growing each day, close as if right beside them.
