The parenting app for first-time mothers, with warm daily guidance across 35 developmental phases. Less second-guessing. More quiet confidence.
You don't need another tracker. You need a quiet, warm place that understands what you're going through.
Instead of doom-scrolling Google at 2am, you'll know exactly what phase your baby is in and what they may need tonight.
A gentle, ad-free community of mothers going through the exact same week. Someone is always awake when you are.
Ask Willo anything. A warm AI companion trained to answer like a knowledgeable friend, not a clinical manual.
Your baby isn't following a generic age chart. They're moving through 35 distinct developmental phases, each with its own rhythm, its own fussiness, its own small magic.
Willo tells you exactly where they are, what's happening in their brain, and what you can gently do to help. So when a week feels hard, you'll know it's a phase, not a failure.

Reviews from mothers on the App Store and around the world.
Willo is the first app that felt like it was made by someone who actually understood what the first year is like. I open it to feel a little more like myself.
"The first parenting app that doesn't feel like it's trying to sell me something. It just feels calm."
Hannah K. · London, UK"I thought I needed more information. Turns out I just needed something that spoke to me kindly."
Ava R. · Byron Bay, Australia"The phase system changed how I see the rough weeks. Now I know they'll pass. That's everything."
Jordan T. · Vancouver, Canada"Ask Willo at 3am is honestly a game-changer. My partner is asleep and I have a friend who gets it."
Emma L. · Melbourne, Australia"The Memory Book broke me in the best way. A year in and I can't believe how small he used to be."
Grace O. · New York, USA"The design alone. I actually enjoy opening the app. No other baby app has ever made me feel like that."
Isabel P. · Edinburgh, UK"I love that it grows with her. We're past the newborn phase and I'm still learning something every week."
Maya S. · Toronto, Canada"The sleep sounds saved our nights. The lullabies are actually beautiful. Not the usual nursery mush."

That sounds exhausting. Luna is mid Phase 10 which often comes with extra fussiness. Let's try a slower afternoon together.
Sleep sounds
A curated library and bedtime routines built with actual sleep science, not white-noise spam.
Memory Book
Private, on your device. Scroll back in a year and you'll be amazed they were ever this small.
Mood Journal
A gentle tap a day. Willo surfaces patterns so you can stop wondering if it's just you.
Happy
Tired
Fussy
Sad
The Village
Ad-free. Anonymous-friendly. Ask the thing you'd never ask your mother-in-law.
Phase-matched games
Short, science-backed play activities matched to your baby's phase. Because play is how they learn.

Curated modules updated for your baby's current window: sleep, brain & body, nutrition, mood, connection, play, wellbeing for you, good-to-know, and the phase itself. Never the same article twice this week.
SleepBrain
Feed
YouNot a generic chatbot. Not a clinical FAQ. Trained on developmental science, calibrated to your baby's current phase, and tuned to the voice of someone who's been there. Ready for the 2am questions you'd be embarrassed to Google.
A visual timeline of your baby's first six years. Each phase named, illustrated, paired with what to expect. So the rough weeks make sense before they arrive.
One photo a day, automatically stamped with the phase, age, and moment. Nothing uploaded, nothing shared. Just yours, compounding into a book you'll cherish. Scroll back after six months and watch them grow.
Nine in-depth modules, personalised to exactly where your baby is right now. Not a generic encyclopaedia. Content that rotates daily and matches the week you're actually in, so you learn what you need, not everything all at once.
What changes when you stop doing this alone.
Motherhood is a community effort. We build Willo so more mothers can feel held. And we share what comes back to us, so more children can be too.
When it's 3am for you, it's 9am for her. Somewhere, another mother is exactly where you are. Willo is used by first-time moms in the US, UK, Canada, Australia, and growing.
Someone is always awake when you are.
Built for the whole journey, not just sleep logs or weekly leaps.

Based on publicly available features as of April 2026. Willo's feature set is designed for the whole journey from birth to age six, with a focus on warmth, community, and phase-based guidance.
If you're wondering, someone else was too.
Willo is free to install and free to onboard. That includes getting to know you, creating your profile, finding your baby's current developmental phase, and exploring the app's core layout.
Some of the ongoing features are part of a premium membership, because they cost real money to run beautifully. We keep pricing intentionally simple and affordable. Think less than one pediatrician visit for an entire year of guidance, sleep support, AI chat, and community. No ads. No data selling. Just a better experience for mothers.
Willo covers birth through age six. The 35 developmental phases are designed to accompany your baby from the first day home through toddlerhood and into early childhood. Most mothers join during pregnancy or in the first three months of baby's life, when the need for a calm, knowing companion is strongest, and many stay on through toddler years for the ongoing educational content and community.
The 35 phases are named developmental windows your baby moves through between birth and age six. Each phase is paired with the social, physical, and cognitive changes happening at that moment, plus gentle guidance on what to expect and how to support it.
Rather than the generic "week 24 milestone checklist" many parenting apps offer, Willo gives you a map of who your baby is becoming. When a hard week hits, you'll know it's a phase, not a failure.
Most parenting apps are trackers or sleep calculators. Willo is a companion.
Huckleberry and Napper focus on sleep log analysis and routines. Wonder Weeks focuses on 10 mental leaps in the first 20 months. Willo covers 35 developmental phases across six years, adds a warm AI assistant (Ask Willo), a private memory book, a mood journal, sleep sounds, phase-matched games, and a supportive community. All inside one calm, ad-free iOS app. The design is warm editorial, not clinical dashboard.
Willo watches your baby's age and phase and tells you automatically. The home screen shows the current phase with a gentle progress bar, notes common behaviors during that window (extra fussiness, sleep disruption, appetite changes), and offers phase-matched support. No need to guess or Google. You'll know ahead of the change, not after it.
If you're mid-regression tonight, Ask Willo can walk you through what's normal, what often helps, and what to watch for.
Ask Willo is an AI parenting assistant trained on developmental science and calibrated to the tone of a warm, knowledgeable friend. It is not a doctor and does not give medical diagnoses. For anything clinical, it will gently suggest speaking with your pediatrician.
Where it shines: the "am I a bad mom" questions, the "what's happening this week" questions, and the 2am "why won't she sleep" questions.
Yes, and many mothers do. Pregnancy is when the quiet comes before the storm. You can set up your profile in advance, explore the phases you're about to experience with your baby, browse the memory book, and use Ask Willo for the early questions you'd rather not ask in a group chat.
Each day you can capture one photo of your baby. Willo stamps it with the date, developmental phase, and age, and organizes your daily frames into a year-long memory book by phase.
All photos stay on your device. Nothing is uploaded, nothing is shared. It's yours, forever.
Yes. Photos stay on your device. Mood logs and journal entries stay on your device. Community posts can be made with an anonymous handle. Ask Willo conversations are not tied to any identity beyond your account.
We do not sell data. We do not run ads. The business model is subscription, not surveillance.
Yes. During setup you can enter your baby's adjusted age (gestational minus premature weeks), which is the age most pediatricians recommend using for developmental tracking. Your phase progression follows the adjusted age so the content meets your baby where they actually are.
Absolutely. Willo works beautifully for partners, co-parents, and family members who want to follow along. Today that happens through separate accounts, with shared profiles on the roadmap. A lot of dads and partners use Ask Willo to get up to speed without feeling judged for asking.
Yes. A portion of every dollar Willo App earns goes to children's disability care. Motherhood is a community effort, and the more mothers feel held, the more families we can help feel the same way.
Not yet. Willo is iOS only today, on iPhone and iPad, available in the US, UK, Canada, and Australia. Android is on the roadmap. Email help@meetwillo.app if you'd like to be told when it launches.
Willo is built by Sonora Labs, an independent studio that makes apps and music focused on nourishing attention and quiet wellbeing. The team's background is in music that calms and design that breathes. Willo is the result of applying that practice to the first six years of motherhood.
Let Willo carry some of it with you. Free to install, on iPhone and iPad.
