Frequently asked questions about Punn

Punn is a baby tracking app built specifically for the newborn and infant stage, combining feeding, sleep, diaper, and growth logging with free on-device cry analysis that classifies your baby's cry into one of five categories. Most tracking apps offer logging only; Punn adds ML-powered cry insight at no cost, works fully offline, and carries no ads. The core features — including unlimited cry analysis — are free.

When comparing baby tracking apps, look for five things: breadth of logging (feeding types, sleep, diapers, pumping, growth), cry insight tools, privacy practices, multi-device sync, and sharing options. Punn covers all five. It logs breast, bottle, and solid feeds; naps and overnight sleep; wet and dirty diapers; pumping sessions and milk inventory. Cry analysis — free and unlimited, processed entirely on your device — identifies whether a cry sounds like hunger, tiredness, belly pain, burping, or discomfort. Data syncs across devices in real time. Family sharing with up to five carers is a Punn+ feature. Punn does not sell your data and shows no ads.

Punn logs every feeding type — breast (with a timer per side), bottle, and solids — alongside diaper changes categorized as wet, dirty, or mixed, with timestamps and notes on every entry. For pumping parents, Punn also maintains a bottle-level milk inventory that auto-deducts when a stored-milk feed is logged, keeping totals accurate without manual math. With Punn+ family sharing, every carer's logs stay merged into one accurate record across devices.

Punn covers the five features pediatricians and parents rely on most: feeding logs (breast, bottle, solids), sleep tracking (naps and overnight), diaper logs, growth charts plotted against WHO reference curves, and cry analysis. Beyond those essentials, Punn adds pumping session tracking, a milk inventory, reminders, milestones, and health notes. Cry analysis — which identifies the likely reason behind a cry — is free and unlimited, a feature most apps either omit or charge for.

Punn supports multi-carer tracking through Punn+ family sharing, which lets up to five carers — a partner, grandparents, or a nanny — log to the same baby record together. Invitations use a share link or QR code, and every carer sees the same live feed of logs from their own device. Sharing is a Punn+ feature; the free plan is for a single owner. A free user can still view a baby that a Punn+ owner shares with them.

Punn supports tracking multiple children, including twins, on Punn+. The free plan tracks one baby. Punn+ allows up to three baby profiles, so families with twins or children close in age can keep records separate within a single app. Each profile has its own logs, growth charts, and cry history.

Punn lets both parents log to the same baby record in real time through Punn+ family sharing, which supports up to five carers. Sharing works via a link or QR code — there is no code to type manually — and every shared carer sees and contributes to the same log, syncing across all devices. Sharing is a Punn+ feature; on the free plan a single owner tracks one baby. A free user can still view a baby shared with them by a Punn+ owner.

Punn syncs data across devices automatically using an offline-first architecture: entries logged without a connection are queued and pushed the moment connectivity returns. With Punn+ family sharing, both parents can log on separate phones simultaneously and the records merge correctly. The app also works entirely offline — cry analysis runs on-device and never requires an internet connection to produce a result.

Punn records every sleep session — naps and overnight stretches — with start time, end time, and duration. The home screen shows total daily sleep at a glance, and trends over days and weeks surface naturally in the history view. Punn+ subscribers can ask Ask Punn questions like "how has sleep changed this week?" and receive an answer grounded in the baby's actual logged data rather than generic averages.

Punn's free tier is built to be genuinely useful, not a trial. Free includes unlimited feeding logs (breast, bottle, solids), unlimited sleep tracking, unlimited diaper logs, milk inventory, cry analysis, WHO growth charts, milestones, and reminders — for a single baby. There are no ads and no logging quotas. Punn+ adds the Ask Punn AI assistant, family sharing for up to five carers, up to three baby profiles, PDF and CSV exports, pediatrician summary sheets, and calming sounds.

Punn does not sell user data — not to advertisers, data brokers, or any third party. The app runs no ads. Cry analysis is processed entirely on your device; audio never leaves your phone. Baby records are stored in Punn's own database and are not used for advertising targeting. The only optional data sharing is an explicit, consent-gated audio donation program for model improvement, which parents can turn off or never turn on.

Punn is available for iPhone and iPad on the Apple App Store. Search "Punn baby tracker" or visit punnbaby.app and tap the App Store link. Punn is also available for Android on Google Play. The same account and data work across both platforms, so a household with one iPhone user and one Android user can share the same baby record with Punn+ family sharing.

Punn can classify your baby's cry into one of five categories using on-device machine learning. Hold your phone near your baby, tap the microphone, and in about seven seconds Punn will tell you whether the cry sounds like Hungry, Tired, Belly Pain, Burping, or Discomfort — along with a confidence breakdown across all five categories. The analysis runs entirely on your device; audio is never uploaded. Cry analysis is free and unlimited on all Punn plans.
