The whole day with your little one — in one calm place.
Sleep, feeding, diapers, growth, and milestones — newborn to toddler, in one place. Fast to log, honest with the numbers, and private by default. Everything stays on your device.
14-day free trial · then $8.99/mo (yearly) or $12.99/mo · No ads, no tracking.
A look inside
Made for one-handed logging at 3 a.m. — and clear enough to make sense of the day.
A feeding timer that's finally right
Most trackers count wall-clock time and over-count a feed the moment your baby pauses or drifts off. LittleRhythm counts only active nursing time, per side, and keeps the screen awake so a long feed in the dark never dims out. Bottles, pumping, and solids live in the same logger.
- Per-side, active-time math — no phantom minutes
- Keep-awake for those 3 a.m. feeds
- Picks up exactly where it left off if the app closes
- Breast, bottle, pumping & solids in one logger
Gentle insights — never alarms
Most parenting apps nag. LittleRhythm opens with what's going well — a longer night, a steadier rhythm — then quietly notes what's worth a look, in plain language.
Every number comes from tested rules on your device. The optional Angel assistant only puts them into friendly words — it never invents a figure or makes a call about your child's health, and it never diagnoses.
- Rules decide the numbers; wording follows
- Correlations & trends across sleep, feeds and mood
- Opt-in AI — de-identified and off by default
- Pediatrician-ready summaries you can share
Naps that don't sneak up on you
Overtired is the enemy of a good nap. LittleRhythm learns your baby's wake windows from what you log and tells you when the next nap is likely — so you wind down before the meltdown, not after.
The prediction comes from transparent rules, not a black box, and adapts as your child grows. Turn it into a reminder and the timing reschedules itself each time you log a sleep.
- Deterministic wake-window predictions
- Reminders that reschedule as you log
- Night vs day kept honest
- Adapts to age and recent pattern
Smart where it counts — safe by design
This is a child-data product, so the intelligence sits on tested rules, not a chatbot's guesses.
Rules decide, AI narrates
Wake windows, totals, trends, and every threshold come from unit-tested code. The optional AI only phrases the result — it never picks a number.
No diagnosis, ever
LittleRhythm describes patterns; it never names a condition or a cause. A quiet pediatrician disclaimer stays on every guidance screen.
Calm, age-aware prompts
When something warrants attention, a rules-based nudge suggests calling your pediatrician — tuned by age, worded to reassure.
Nothing trains on your child
AI is opt-in and off by default. Prompts are de-identified — ages in weeks, counts, intervals — with zero retention and no training.
One app that grows with your child
The newborn haze and the toddler years need different things. LittleRhythm shifts the loggers, guidance, and dashboard to fit the stage you're in.

- Fast feeding & diaper logging
- Sleep and wake windows
- Pumping & bottle amounts

For the 2 a.m. moments
The night feeds, the nap that finally sticks, the tiny wins — LittleRhythm keeps up quietly, so you stay in the moment instead of buried in an app.
No account, nothing kept on a server, and nobody selling your family's story.
See what's includedSimple enough for the hardest days
You shouldn't have to think about the app when you're running on two hours of sleep. It's built to disappear into the moment.
Log in seconds
One-handed taps, a movable quick-action button, and voice logging for when both hands are full. Forgot to start a timer? Backdate it — nothing is ever lost.
See the rhythm
A live dashboard and a filterable timeline turn scattered taps into your child's real day, with today's totals at a glance.
Get gentle guidance
Calm, rules-based nudges for the next nap and routine — wins first. Share the load with a co-parent, and everyone sees the same day.
Everything in one place
One home for every kind of log — newborn to toddler. It all works offline, and it all stays yours.
Sleep & naps
Night sleep and naps with wake windows and a clear day-vs-night picture. Tap to log or run a timer — it survives even if the app closes.
Feeding, done right
A side-aware breastfeeding timer that counts active time only, plus bottles, pumping sessions, and solids — with amounts, durations, and honest daily totals.
Diapers & health
Wet and dirty diapers, temperature, medications with doses, and free-text notes — everything a rough night or doctor's visit calls for.
Growth in perspective
Weight, length, and head circumference plotted as your child's own trend against a gentle reference range — never reduced to one scary number.
Milestones & stages
An age-appropriate milestone checklist and first solids — then potty training, meals, moods, and activities as your child grows.
Caregiver sync
Share logging with co-parents and carers across phones, end-to-end encrypted — so nobody double-logs the 2 a.m. feed.
Fast & hands-free
One-handed taps, a movable quick-action button, and voice logging when your arms are full. Metric or imperial, in 10 languages.
Calm reminders
Nap and feeding nudges that reschedule as you log — with anti-overwhelm controls so the app never becomes one more stressor.
Yours to keep
Encrypted export/import, pediatrician-ready reports, and CSV. Move phones with everything intact — or delete it all, permanently, in one tap.
Why LittleRhythm
We built it after years with the popular trackers — Huckleberry, Baby Connect, Napper and the rest. Four things we do differently.
Truly private
No account, nothing on a server. Your child's data lives only on your phone, encrypted.
Feeding math that's right
Counts active nursing time per side — not the clock — so your totals are actually true.
AI you can trust
Tested rules compute every number; Angel just puts it in plain words. Never a diagnosis.
Nothing is deleted
Every edit keeps its history, so you can fix a mistake without losing the record.

Questions, answered
Is my data really private?
Yes. Your care logs are stored only on your device, in encrypted form. There's no account, and we don't collect your logs on a server. A few optional features (AI insights, crash reporting) can send limited, de-identified information — they're off by default and you control them. Read the full Privacy Policy.
How much does LittleRhythm cost?
You get full access during a 14-day free trial. After that, LittleRhythm Pro is $8.99/month billed yearly ($107.98/yr, save $48 vs monthly) or $12.99/month — the complete app either way (all logging, unlimited children, caregiver sync, AI insights, predictions, reports, and backup). Cancel anytime.
Does it give medical advice?
No. LittleRhythm describes patterns and never names a condition or diagnoses. When something is worth checking, it calmly suggests contacting your pediatrician. It is not a medical device.
Can my partner and I share logging?
Yes. You can track multiple children and share logging across caregivers' phones with end-to-end-encrypted sync — so everyone sees the same day.
What happens to my data if I switch phones?
Create an encrypted export (or use your platform backup) and import it on the new device. Your data is portable and yours — and "Delete all my data" removes everything permanently in one tap.
How is the AI kept safe?
Every number is computed by tested rules on your device; the AI only phrases it in plain language. Requests are de-identified (ages in weeks, counts, intervals — never names or photos) and configured for zero retention and no model training. It's opt-in and off by default.
Do I need to be online?
No. All logging, the dashboard, the timeline, reminders, and wake-window suggestions work fully offline — the app doesn't depend on a server to do its job. Only the optional AI phrasing and subscription checks use the network.
Why does the feeding timer matter so much?
Because a timer that counts wall-clock time over-counts every feed where your baby pauses or dozes. LittleRhythm counts only active nursing time, per side, so the totals you rely on — and share with a pediatrician — are actually true.
How many children can I track?
As many as you like — every child is included in your subscription. Each gets their own stage, dashboard, and timeline, and the home screen shows the whole family at a glance.
What happens after the free trial?
Your 14-day free trial unlocks the complete app. When it ends, continuing needs a LittleRhythm Pro subscription ($8.99/mo billed yearly, or $12.99/mo). If you don't subscribe, tracking is paused — but your data is never trapped: you can always export it or delete it, restore a purchase, or manage your subscription. Cancel any time before the trial ends and you won't be charged.
What languages and units are supported?
Ten languages, with metric or imperial units (kg/lb, cm/in, °C/°F) — chosen per family. A dark theme is first-class for those night feeds.
Can I keep it private on a shared phone?
Yes. An optional biometric app lock (Face ID / Touch ID / passcode) keeps your family's data private, and deleting the app or your data leaves nothing behind on a server because there was never anything there.
Private by construction
Privacy isn't a setting here — it's how the app is built. No account, no server collecting your child's logs, so there's nothing to leak, sell, or subpoena. A few optional features can send limited, de-identified data; they're off by default.
- No advertising or third-party tracking SDKs
- No precise location, ever
- Encrypted on device; optional biometric lock
- Export what's yours, or erase it all in one tap
