The baby tracker for two parents

Baby care,
logged together.

Duet lets both parents log sleep, feeds, diapers and pumping in one tap, and keeps you in sync, even at 3 a.m.

Coming soon to theApp Store
Two exhausted parents on a sofa at night, one holding a crying baby, the other yawning over a scribbled note.

Newborn life is a blur.

Feeds, naps and diapers around the clock, split between two tired people. By 3 a.m., nobody remembers who did what, or when.

Duet remembers, so you don’t have to.

Log it in one tap.

Start a sleep, a feed or a pump the moment it begins, and log a diaper as it happens. Duet keeps the time, the side and the details, so you can get back to the baby.

Two parents. One log.

Invite your partner with a six-character code. Every feed, nap and diaper shows up on both phones in moments, with who logged it. No more “did you feed her?” texts at 4 a.m.

  • Either of you can start, stop or fix any entry.
  • Offline? It saves on your phone and syncs when you’re back.
  • Always clear who started a timer and who changed what.

Follow every feed at a glance.

Sleep and feed timers live on your Lock Screen and in the Dynamic Island. Switch sides or pause without unlocking. And when one of you starts a timer, it appears on the other’s phone too.

At night, one parent sleeps while the other feeds the baby a bottle by the glow of a moon night-light.

Night mode

Made for the midnight shift.

A dim, gentle screen with big controls, for feeds in the dark. One tap starts a sleep. Then rest.

A little less light. Everything you need.

See their patterns emerge.

History by day, week and month, and trends that turn a blur of entries into something you can read. Spot the longer stretches, and see how the days are changing, together.
