Nestly does the remembering, so you can be present. Features marked Premium are included in the 15-day trial.
-
One-tap logging
Feeds (breast, bottle, solids and other drinks), diapers, sleep, medication doses, temperature, growth, baths and active play. On Home, tap any tile on the Today card to log it right there.
-
Today and Progress
Green, amber and red against age-based daily targets, and pace that knows what time it is. Progress compares each number with this time yesterday.
-
Real-time sync
A feed logged on one phone shows up on everyone else's in seconds. Entries save on your device first, then sync to your household.
-
Growth and milestones
Log weight, length and head circumference and tick off milestones from birth to 3 years. The Growth Journal keeps a photo for each month.Journal: Premium
-
Doctor Visit PrepPremium
A checkup-ready summary of feeding, sleep, diapers and growth, plus your own notes and questions. Share it, copy it or print it as a PDF.
-
Insights and AI summariesPremium
Charts for night wakings, bedtime, wake windows, intake and growth, each with a plain-language takeaway. Ask Nestly questions about your baby's logs. AI answers are general guidance, not medical advice.
Sleep
A sleep plan built from your baby, not a chart
Age tables are only the starting point. As you log, Nestly learns how long your baby is happy awake and plans the day around the bedtime you set.
-
Wake windows from your baby's own data
Next-nap timing uses your baby's recent wake windows. A science-based age range is used only until there's enough history.
-
Day Plan with catnaps that protect bedtimePremium
Naps, feeds and activities for the day. If the last stretch before bed would run too long, Nestly fits a short, age-appropriate catnap so bedtime can stay where you want it.
-
Catnap heads-up
Part of the Day Plan: a reminder 20 minutes before a planned catnap (wake-up reminders can be turned off). While a catnap is running, Home shows when to wake your baby so it doesn't eat into bedtime.
-
Night-waking tracking
When a night sleep ends, one tap records "slept through" or how many times your baby woke. Insights (Premium) charts the last 14 nights and compares this week with last.
-
Sleep CoachPremium
Looks for patterns in your baby's sleep, such as short naps, frequent night wakings, an inconsistent bedtime, long wake windows or sleep debt, and suggests a 4-day focus plan. Every suggestion says why, with its source in published sleep research and AAP guidance.
-
Sleep that's split by a night feed
A night broken by a feed still counts as one night, even across midnight, so averages reflect how your baby really sleeps.
Nestly's sleep guidance is general information based on sleep science. It is not medical advice. Talk to your pediatrician about any concern about your baby's sleep or health. On the web, reminders appear while Nestly is open.

Questions
Good to know
Is there an iPhone or Android app?
Not in the app stores yet. Nestly works today in the browser on any phone, tablet or computer at app.nestlyrhythm.com. You can add it to your phone's home screen from your browser's share menu.
What happens when the 15-day trial ends?
You move to the free plan automatically. Nothing is charged and your logs aren't deleted: entries older than 30 days are hidden until you upgrade, and caregiver access pauses.
Who can see my baby's data?
Only the people you add to your household, with the access you choose. We don't show ads and we never sell your data. Read the privacy policy for the details.
Is Nestly medical advice?
No. Targets, sleep guidance and AI answers are general information. Always talk to your pediatrician about your baby's health, and call emergency services in an emergency.
