Offline-first, not offline as an afterthought
Many apps need a network or an account before the basics work. Lilu is built so the full log runs on the device: airplane mode, dead Wi-Fi, and 3 a.m. in the nursery are normal, not edge cases.
Baby care, calmly organized
One gentle place for every log that matters.
Lilu runs fully on your phone when you want it to—no signal, no uploads: your complete log can stay on the device and never touch our servers. Turn on cloud sync only when you are ready for shared care and the web portal. Every feature is free, with no ads.

Offline first. Cloud when you want more.
Most families only need the phone. Everything else is optional—and you can switch modes when your life changes.
Everything can stay on the device
In full offline use, your logs live on your phone and do not leave it. There is no background upload, no dependency on our servers, and nothing for us to monetize—because the data never gets there.
For many parents, that alone is enough: one calm timeline, always in your pocket.
Optional sync unlocks shared care
When you enable cloud, you get a single shared timeline without passing the phone around at midnight: each guardian uses their own device, entries merge in one place, and you can see who logged what.
- Multiple caregivers on their own phones—same baby, one story
- Web access for charts and heavier workflows—aimed at power users who want an admin-style portal
- Go back to fully offline whenever you want—you are in control
All features are completely free. No ads, no upsells.
Lilu is built to be useful on day one without a subscription—and honest about what might change only for online-heavy use in the future.Why should you use Lilu?
Lilu is new—so instead of social proof, here is what it does differently from the typical always-online, one-layout-fits-all baby tracker.
If you use cloud, your baby's timeline is not readable by us
Plenty of trackers store your entries where the vendor can read them. With cloud enabled, Lilu encrypts baby log content on your device before it touches our infrastructure—we route sync and see what we need to run accounts, not your child's journal.
A dashboard you reshape, not a fixed tab bar
Most trackers lock you into their idea of what matters first. Lilu uses pages and the same chips you already tap in the app so you can arrange what you actually use—feeds, sleep, meds, whatever your day looks like.
About three taps—not a mini form every time
The actions you repeat all day are meant to finish in very few taps, with almost no typing. That is something I never got from other trackers, and it matters most when you are one-handed, your baby is asleep on your arm, and you still need to log or nudge a feed amount without waking anyone.
Multiple guardians, one baby
Optional sync gives each caregiver their own login and device while the baby stays a single shared timeline. Guardians can be labeled—mother, father, nanny, and so on—so every entry carries who logged it and when, which adds context most trackers never surface cleanly.
Multiple devices, one baby
You are not limited to one handset per guardian. With sync on, the same account can open the same baby on multiple phones or tablets (and the web), so logging stays natural whichever screen is in reach.
A web app for power users
Beyond the phone, the web portal is for when you want heavier workflows: richer visualizations than fit on a small screen, print-friendly layouts, and backup and restore so you can treat the log like real records—not just a daily diary.
From moment to insight
Start on the phone. Add cloud when your family or workflow needs it—then use the web for the heavy lifting.
Privacy is not an afterthought
Your baby's log stays yours by default. Here is how offline and optional online modes differ.
Privacy policy (legal) — formal terms for the service and data handling.
Fully offline
If you use Lilu fully offline, your logs never leave your phone. Nothing is uploaded, so there is no cloud copy for us—or anyone else—to access. You do not need to think about encryption on our servers or what we can see, because your baby's data never gets there. Period.
Cloud & web (when you opt in)
The details below only apply when you choose online mode: optional cloud sync and the web portal. Then Lilu follows zero-knowledge principles—we do not see your baby's health or log data, only basic account details needed to run sync. Baby details are encrypted on your device before anything touches the cloud, and only your devices can decrypt them. There are no ads and no third-party trackers funding the product.
- OfflineNothing is sent to Lilu—the simplest possible privacy story
- OnlineClient-side encryption; we cannot read your child's timeline
- OnlineEnd-to-end encrypted sync and secure unlock on each new browser
- OnlineDelete your account completely at any time from the app
- ProductNo ads—every feature is offered free
Built by a parent, for daily use
Lilu did not start in a boardroom—it started at a changing table.
After trying many baby trackers, none of them felt right—too noisy, too rigid, or too eager to ship my family's data somewhere I did not control. So I built Lilu around what I actually needed, and I still use it every day to track my son.
There is no better assurance than the developer being the most active user of the product. If it is frustrating at 3 a.m., it gets fixed—because I am there too.
Frequently asked questions
Straight answers about staying free, what could change at scale, offline use, privacy, and how Lilu came to be.
Why is Lilu free?
It began as software I wrote for my own family—daily tracking, not a product roadmap. Opening it up made sense because the same problems are universal, and a paywall would work against the goal of keeping logging simple and calm.
There are no ads and no "growth hacks": if Lilu is useful, that is enough. The codebase and hosting are sized so it can stay that way for normal use.
Will you ever charge?
There is nothing on the roadmap that turns core features into a subscription. The honest constraint is infrastructure: encrypted cloud sync and the web app cost money to run at scale. If usage ever grew far beyond what is reasonable to self-fund, only then might something change—and it would be aimed at online-heavy use, not at charging you to keep a local log on your phone.
What is the difference between offline and cloud?
Offline mode keeps everything on your phone. Nothing is uploaded, and there is nothing for us to see or sell on our side. When you choose cloud sync, data is encrypted end-to-end for your baby's records so multiple guardians can contribute from their own phones, you can see who entered what, and you can unlock the web portal for charts and heavier admin-style workflows. You can stop using cloud and go fully offline again whenever you want.
What if I need a feature Lilu does not have yet?
You can submit feature requests from the web app while signed in. Each request is visible to all logged-in users, and people can vote so it is easy to see what the community wants most. Lilu is a small project with limited time—there is no guarantee—but when something is clearly in high demand, I may implement it.
Who built Lilu?
Lilu is an independent project built by a parent who tried many baby trackers and never found one that felt right—so this app was built for real daily use first. The same person still tracks their son in Lilu every day. There is no stronger test than the developer living in the product alongside you.
