Every baby tracker logs feeds, sleep and diapers. Livia (Livia Baby Tracker on the App Store) does the basics in a tap, and then does seven things that most trackers don't, or charge for. Everything other trackers put behind a premium plan is free in Livia, with no ads and no card; the one thing Livia will ever charge for is Ask Livia, the assistant that's coming. Get early access.
1. It estimates the next nap and bedtime from your baby's own rhythm
Home shows how long your baby has been awake and when the next nap is likely, as a range, "around 12:30–1:00". It starts from typical awake times for the age and moves them by how your baby's last week went. Older babies get a daily schedule, and bedtime comes from the one your family keeps. If a nap probably went unlogged, Livia asks instead of guessing. Huckleberry sells this as SweetSpot in its paid plans; in Livia it's free. How the estimate works.
2. It catches the slips you make half asleep
Typed 1200 ml? "Did you mean 120 ml?" You and your partner both logged the same feed? Livia asks which one to remove. A sleep timer running since this morning gets a gentle check. A long stretch with no nap logged gets a question, not a gap. Every check is about the log, never about the baby, and every fix is one tap. Undo lives in place for a minute, not in a toast. The full list of checks.
3. It keeps the night together
Most trackers cut last night's sleep at midnight, so it is never one number. Livia counts a sleep that starts in the evening as that night's, in the morning it ends in, wake-ups included. A day in History is last night plus its naps, the way you think about it. Why that matters.
4. Both phones, same night, with no family plan
Invite a partner, grandparent or nanny by email. Each has their own sign-in, every entry shows up on every phone within seconds with the name of who logged it, and a timer started on one phone is running on the other. On your own phone, a running timer sits on the lock screen too, with buttons to switch sides or finish the feed. Because Livia never overwrites an entry, two phones can't conflict, even after a day offline. Baby Daybook, Glow Baby and Baby Tracker charge for this; Livia doesn't. How sharing works.
5. It logs with no signal
Every entry is saved on your phone before anything else happens. A feed in a basement, on a plane or at a cabin is recorded the moment you tap, and syncs when you're back online. Nothing you log ever waits on a spinner.
6. It tells you when a day was normal, and names the source
Insights looks at the last complete day and says what stood out: the longest night so far, or that yesterday's feeds were inside the range the American Academy of Pediatrics publishes, in your baby's name, with the page linked. A count below the range is a prompt to check the log ("Missed any?"), never a verdict. A sleep total outside it says days vary and points to your pediatrician if it keeps up. Livia will never say "low", "too much" or "should", and it will never invent a problem to sell you something.
7. It stays calm
Dark, one-handed, quiet. No shop, no community feed, no upsell between you and the Log button. Turn off what you don't track and those buttons disappear. Ages in months and days, adjusted age if you use it, metric or imperial per phone, WHO growth charts with "about the Nth percentile" shown and never flagged. Milestones, vaccines and medicine are records you keep, with no schedules or "due".
What Livia doesn't do, yet
No export, no sleep-training plans. (Importing is the other way round: Livia reads the history you export from Nara Baby or Huckleberry; see Livia vs Nara Baby and Livia vs Huckleberry.) The assistant, Ask Livia, is coming soon and will be the one paid part of Livia: everything in this list stays free. Livia is in early access before its App Store and Google Play launch, so it is new. The person building it reads every reply.
Why download it now?
Because the habit forms in the first weeks, and the next-nap estimate gets better with every logged sleep. Early access is the full app, free, with no ads and no card, and your account and log carry over when Livia reaches the App Store. Get early access. For how it stacks up against the apps you've heard of, read Huckleberry vs Nara Baby vs Baby Tracker vs Livia, or the head-to-heads with Huckleberry and Nara Baby.
Livia tracks routines; it isn't medical advice. If you're worried about your baby's health, talk to your pediatrician.
