A quick look at the app

A calm heads-up

What happened — and what's likely next

Rhythm turns the day's logs into one quiet glance: how long since the last feed, how long awake, when a nap tends to come.

Gentle nudges are drawn from your baby's own patterns — and they're always kept separate from what actually happened. A prediction is never dressed up as a fact.

Your data, your patterns — not clinical rules
New · Rhythm AI

A smart chat that knows your baby's day.

Ask how the night went, when the next nap is likely, or whether she's eating less than yesterday. Rhythm AI reads your own logs, shows what it used, and turns “just gave her 120 ml” into a log you confirm with one tap.

  • Answers from your logs, and shows the logs it used
  • Spots what's likely next and compares days for you
  • Say what happened — it prepares the log, you tap to save
  • Everyday questions too: soothing, routines, what to try
  • Health worries get a calm, approved pointer to your doctor
Opt-in · names never leave the phone Not a doctor
New · Smart Voice Log

Hands full? Just say it.

Hold the + button, or tap “Say it instead”, and say what happened. Rhythm hears every activity in one sentence — up to three at once.

Each one gets its own card to check: the time, the amount, wet or dirty. Fix anything with a tap, then log them together — and undo if you change your mind.

The cry helper

Not sure what the crying means?

When you're stuck at 3am, the cry helper listens for a moment and gently suggests what might be worth trying first — a calm starting point, never a diagnosis.

Sent once for analysis, never stored

A gentle helper for the guesswork — not medical advice. You know your baby best.

For two parents

Two parents, one rhythm.
Even at 3am.

Whoever's on duty logs it, and the other just knows. Split the night, and only the person on shift gets woken.

  • Every log syncs to both phones instantly
  • Night Shift: only the on-duty phone gets nudges
  • Grandparents or a sitter get a simpler view

Insights, not verdicts

See the patterns, share them with the doctor

Rhythm turns weeks of little logs into a clear picture of your baby's own trends — and a tidy report when the pediatrician asks.

Fairness between caregivers

A gentle, judgment-free look at who's been doing what. Not a scoreboard — just a shared, honest picture that makes splitting the load easier to talk about.

A report for the pediatrician

Pick a date range and export a clean summary — CSV for their records, or a print-friendly PDF for the visit. Only what you logged, never predictions.

You choose the window

Last 7 days, the whole month, or a custom range around a visit — the summary reshapes to exactly the stretch you need.

Insights reflect your baby's own patterns — a helpful mirror, not a clinical "normal." For anything health-related, your pediatrician always comes first.
