Everything the day needs, together

Two of you,
or three generations.

From couples sharing a home to households with children and pets, and grandparents living far away. Adding a child is optional, and every family picks the parts it uses.

01

Memories

Today's little moment,
for everyone.

Photos, videos and diary entries in order. Comments and reactions mean family who live far away can share the moment too.

If you have children or pets

One tap
to log the day.

Feeds, sleep, nappies and temperature, one-handed. Height and weight become charts you can look back on. Add as many children and pets as you like — or none at all.

Easy to keep up with.

Chores and to-dos

Ask someone to take the bins out or do the shopping, and they reply "I'll do it" or "Can't do it". Regular chores repeat on their own.

Wishes

Share who's buying what, how many, and by when — with a preview image. No more two of the same present.

Photos and videos, always protected

Not even we
can open them.

  • Encryption is always on. There's no setting to turn it off
  • Only approved family devices can show photos and videos
  • Location data in photos is removed before encryption by default
