All features

Built for two people sharing a baby

Four feature areas. One shared log. Nothing you don't need.

What Xoul does

Four things, done well

Multi-Caregiver Log

Real-time shared timeline with caregiver attribution on every entry. Your partner, grandma, the nanny — the hand-off summary is always current. No more "did you log it?" at 4am.

How it works

Sleep Window Estimates

A weighted moving average of your baby's own logged wake windows. Not a sleep coaching program — an honest estimate of when sleep is probably available. Xoul does not tell you to let your baby cry.

How it works

Feed & Formula Tracking

Volume in ml or oz, feed type (formula, breastmilk, pumped), timing, and caregiver attribution. See daily totals and 7-day volume trends. Exportable to PDF for your pediatrician appointment.

How it works

Pediatric Flags

Seven observations that warrant calling your pediatrician — not diagnoses, not notifications for every diaper rash. Feeding refusal, sustained volume drop, extended inconsolable crying, and four others. Curated to stay trusted.

Feature 1

Multi-Caregiver Log

Everyone in your household — your partner, a grandparent, a nanny — can log feeds, diapers, sleep, and notes. The timeline updates in real-time for everyone.

You see who logged what and when. No more disagreement about whether she was fed an hour ago.

Feature 2

Sleep Window Estimation

Xoul looks at your baby's recent sleep history and estimates when the next sleep window is available. It's pattern recognition, not a sleep training program.

We are explicit about what this is and what it isn't. No method. No crying advice. Just a map.

Feature 3

Feed & Formula Tracking

Log feed volume, timing, and type across all caregivers. Whether your partner gave 90ml at 2am or grandma did a 120ml at noon — it's all in one place.

See timing patterns over time. Spot if feeds are spacing out. Track volume trends for the age band.

Feature 4

Pediatric Flags

Seven observations, curated with care. These aren't diagnoses — they're reminders to call your pediatrician. The list is short by design.

Xoul does not flag mild diaper rash, occasional spit-up, or brief fussiness. It flags things that a pediatrician would want to know about — the short list that actually signals something.

Xoul is not a medical device. These flags are reminders to call your pediatrician, not diagnoses.

See the flag list

Feeding refusal

No feeding for 8+ hours in a newborn (under 3 months).

Significant sleep disruption

Sudden change in sleep pattern combined with signs of distress.

Extended inconsolable crying
