The challenge
In the first months, parents make decisions tired and at night: is the baby hungry, overtired, uncomfortable? The information that would help—when the last feed was, how long the baby has been awake—is scattered across memory, notes and different people. Most tracking apps only record; they do not help interpret.
The approach
Lullai puts every care record on one timeline and uses it as context for AI. A cry recording is not analysed on its own but together with the baby's age and the latest feeding, sleep and diaper entries. The result explains possible needs with the strength of the evidence, alternatives and the level of uncertainty, suggests soothing steps and runs a safety check. The app supports observation; it does not diagnose. AI calls and subscription checks run on the server, so no key ships in the app.
What was built
- 01
Context-aware cry analysis
A short recording plus a few questions, weighed against age and recent care records.
- 02
Smart sleep window
Awake time and an age-based estimate of the next sleep window, with corrected age for premature babies.
- 03
AI parent assistant
Answers grounded in the baby's own care records, with referral to professional help when safety is at stake.
- 04
All-in-one tracking
Feeding, sleep with timer, diapers and growth; several baby profiles; entries keep working offline and sync later.
- 05
Family sharing and handover
Invite a partner or caregiver, manage permissions and see who logged the last feed, nap or change.
- 06
Insights and routines
Trends and care reports, weekly development cards, soothing sounds and personal reminders.
The outcome
Lullai is published on Google Play in its second major version, available in 13 languages with an in-app subscription, and developed continuously.
