LilSense — Understand your baby's needs before they cry
The smart baby tracker that learns your baby's patterns and predicts what's next. Built on WHO & CDC research. Designed for exhausted parents — whether it's 3am feedings, unexpected growth spurts, or sleepless nights.

Apple App Store · Best New Apps & Updates
New parents are exhausted
Running on 4-6 hours of fragmented sleep makes everything harder.
Memory Fails
“When did I last feed her?” Sleep deprivation causes genuine amnesia. You can't remember what happened 2 hours ago.
Patterns Hidden
With 15-20 daily events, your brain can't spot the patterns. But they're there, waiting to be discovered.
No Permission to Rest
You don't want data. You want to know: “Can I sleep now? When will she wake up?”
Log. Learn. Predict.
LilSense works the way your exhausted brain needs it to.
One-Tap Logging
Beautiful illustrated buttons for feeds, sleep, and diapers. Log events in under a second, even at 3am.
We Learn
LilSense uncovers your baby's unique patterns. Blends WHO research with YOUR baby's data.
You Rest
“She'll wake 6:15-6:45am” — now you can sleep without the anxiety of not knowing.

OLED black screen with dimmed quick-log buttons. Your partner stays asleep while you log events in near-complete darkness.

Everything you need
Every feature designed for exhausted brains and dark rooms.
One-Tap Quick Logs
Beautiful illustrated buttons for feeds, sleep, and diapers. Log events in under a second, even at 3am.
Smart Predictions Beta
We show time ranges, not false precision. Like a weather forecast: “She'll likely wake between 6:15-6:45am.”
Partner Sharing Coming Soon
Share your baby's profile with your partner. Both see the same data, predictions, and can log events. No more “Did you feed her?” questions.
Privacy-First
Your data is encrypted and secure. We never sell your data or use it for advertising. COPPA compliant.
Built on real research
Our predictions are based on WHO guidelines, CDC recommendations, and peer-reviewed studies — not made-up numbers. We show you exactly what research backs each prediction, and we're transparent when evidence is limited (like wake windows, which have no scientific studies).

How accurate are the Smart Predictions?
Smart Predictions (currently in beta) improve as LilSense learns your baby's patterns. After about a week of logging, most parents see predictions within 15-30 minutes of actual times. We show confidence levels so you know how reliable each prediction is.
Where do predictions come from?
Predictions blend WHO guidelines, CDC research, and your baby's individual patterns. We cite all our sources in the app — no made-up numbers.
Can my partner use it too?
Coming soon! Partner sharing will let you both see the same data and log events together. No more “Did you feed her?” conversations.
What parents are saying
Real feedback from real parents.
“The Night Mode is genius. I can log a feed without waking my husband or blinding myself. Finally an app that gets what 3am actually feels like.”
Sarah M.
Mom of 4-month-old
“I love that the predictions are transparent about what research they're based on. No other baby app does that. It told me my son would wake at 6:30 — he woke at 6:22.”
James R.
Dad of 7-month-old
“Three taps. That's it. I tried Huckleberry and Baby Tracker before this — way too many screens. LilSense respects that I have zero brain power at 3am.”
Priya K.
Mom of 2-month-old
