Founding Families launch: Lifetime is $34.99 (reg. $49.99) through Sept 17 — all of Pro, one-time purchase. Tracking is free forever. No account, no data collection.
Private. Precise. Built for 3 AM.
Lactis is the baby tracker for parents who want their family's data to stay theirs. It's made by Hypnox Technologies, and our first rule is simple: Hypnox runs no servers for your data. Everything lives on your devices and in your iCloud. No account, no sign-up, no analytics or tracking SDKs. Open the app and log your first feed in seconds.
BUILT FOR 3 AM
One-hand logging that works in the dark — big targets, night-friendly colors, zero friction. Timers keep running on your Lock Screen with Live Activities, so a night feed never needs the lights on.
LOG EVERYTHING THAT MATTERS — FREE
- Feeds — breast or bottle, with side tracking and a suggested next side
- Sleep, diapers, pumping, tummy time, supplements, medications, temperature
- Growth — weight, length, and head circumference
- Milk stash manager for pumped milk
- Full raw history with export and import
WORKS EVERYWHERE YOU ARE
Widgets, Live Activities, Siri & Shortcuts, and a full Apple Watch app — log a diaper from your wrist without waking the baby. All free.
SHARE THE LOAD
Invite a caregiver — a partner, grandparent, or nanny — and everyone stays in sync through your iCloud, not our servers. Shift handoffs show the next caregiver exactly what happened: last feed, suggested side, last nap, diapers today.
LACTIS PRO — WHEN YOU WANT MORE
- Patterns — feeding and sleep rhythms come into focus
- Sleep Tide — sleep windows predicted from your baby's own rhythm
- Growth percentile charts (WHO and CDC)
- PDF reports for your health care provider or daycare
- More caregivers and more babies
Lactis Pro is $5.99/month with a 7-day free trial; it auto-renews unless cancelled at least 24 hours before the current period ends, and you can manage or cancel anytime in your Apple Account settings. Lactis Lifetime ($49.99) is a one-time purchase that unlocks the same features.
YOUR DATA, ACTUALLY YOURS
Your data is encrypted in transit and at rest. With iCloud Advanced Data Protection turned on — for you and your caregivers — it's end-to-end encrypted. We can't read your data, sell it, or lose it — we never have it.
Lactis is a record-keeping tool, not a medical device, and nothing in it is medical advice. Always consult your baby's health care provider.

As a first time mommy, this app has been an absolute lifesaver. It’s so easy to use :) I can log everything with just one tap, even while holding my newborn in the middle of the night.The pump and med/supplement reminders are especially helpful for making sure nothing gets missed. I also love being able to export a PDF of all the data to share with our pediatrician, so I don’t have to rely on my memory during appointments.The sleep forecasting feature has been surprisingly accurate and has genuinely helped me plan my days and nights around my baby’s schedule. I really appreciate that my baby’s data is protected with end to end encryption on my device, and the fact that the free version includes Apple Watch logging is a huge plus.Highly recommend this to new parents looking for an easy, stress free way to track their baby’s patterns, routines, and health metrics without feeling overwhelmed!

Thank you. Glad one-tap logging still works with a newborn in your arms at 3 AM, and that the pediatrician PDF is backing you up at appointments instead of memory alone.
A Lifesaver for New Parents—Especially Twin Parents!

As a new parent to a beautiful set of twins, I can honestly say this app has been a lifesaver! Keeping track of everything with two little ones can be overwhelming, but this app has been a total game changer for our family. It makes it so much easier to keep track of feedings, routines, and all the little details that come with caring for two babies. It has helped us establish a routine and made our days feel much more manageable. I’m so grateful we found this app!
Developer Response
Thank you. Two babies at 3 AM is why two-baby logging and caregiver sync are free. Your data stays on your devices and in iCloud. We never have it. Glad it’s helping you find a rhythm.
So helpful!

I really love how easy this app is to use! You can keep track of a baby’s feedings, sleep, diapers, pumping, notes, and more, all in one place. The reminders and notifications are really helpful too, and I love that privacy is a priority. It makes it so much easier for parents and caregivers to stay on top of everything throughout the baby’s day!
Developer Response
Thank you. Glad it’s easy to keep feeds, sleep, diapers, and pumping in one place, and that privacy is the part that stuck. Caregivers stay in sync through your iCloud. We never have the data.
