Private.
Precise.
Built for 3 AM.

Lifting the new-parent fog.
Which side was last? How long has she been asleep? The answer is already on your Lock Screen — before your eyes even focus.
Night Mode
A dim, warm-shifted interface that won't wreck your night vision — or wake the baby.
One-handed logging
Big targets, zero typing. Feed, sleep, or diaper in a tap or two.
Side memory
Lactis keeps track of which side is next, so you don't have to guess at 3 AM.
A real Lock Screen at an actual 3:04 AM — the timer lives there. No unlock, no hunting.
Log everything. A tap or two.
Every log type below is free, with timers that keep running in the background.
Feeds
Breast, bottle, or solids. Both sides, timed, with side memory built in.
Sleep
Naps, nights, and the wake-ups in between — start and stop from anywhere.
Diapers
Wet, dirty, or both. Two taps, then back to bed.
Pumping & stash
Track sessions and manage your milk stash — what's fresh, what's frozen, what's next.
Health basics
Meds, supplements, temperature, and tummy time — logged in seconds.
Growth
Weight, length, and head size, kept alongside everything else.
Everything above is free — forever. Full history, local export, up to 2 babies, you + 1 caregiver.
Made for your Apple devices.
Built natively for the places you already look — all of it free.
Apple Watch app
Start a feed or log a diaper from your wrist — without picking up your phone or waking the baby.
Live Activities & Dynamic Island
Running timers stay on your Lock Screen and in the Dynamic Island. No unlocking, no hunting for the app.
Widgets, everywhere
Last feed, sleep status, and quick actions on your Home Screen and Lock Screen — at a glance.
Siri & Shortcuts
"Hey Siri, log a wet diaper." Done — hands full, lights off.
See it in action.
Ten screens from the shipping app — dark by default, legible at arm's length, honest about what's a forecast.
…and on your wrist — start a feed or log a diaper without picking up the phone.
Your baby's data stays yours — by design.
Hypnox runs no servers for your data. Everything lives on your devices and in your iCloud.
Most trackers upload your baby's life to a company database. Lactis was built so that can't happen — there is nothing on our side to upload to.
Encryption: 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.

| What the developer sees | Nothing | Logs, patterns, identity |
| Account required | None | Usually |
| Ads or data sales | Never | Depends on the app |
Ready for the big picture?
Capturing is always free. Pro turns the logs into answers — and makes room for a bigger household.
Sleep Tide
A gentle forecast of your baby's next sleep window, drawn from your own logs — it learns your baby's rhythm and keeps learning as they grow.
A forecast, not a promise — babies keep their own counsel.
Patterns
Trends across feeds, sleep, and diapers — see the week, not just the night.
Growth charts
Percentile curves on WHO and CDC references as your baby grows.
Visit Kit
A clean doctor visit briefing — your baby's recent history as a tidy PDF for the doctor or daycare.
Bigger household
Add a third caregiver and beyond, and track three or more babies.
Private tracking is free. Answers arrive in Pro.
Capture is always free — you pay for outputs and household scale, never for logging.

Built by a parent at 3 AM.
Lactis is made by Hypnox, a small independent studio — built by a new parent who was living the 3 AM feed and decided it deserved better software. No investors pushing growth hacks, no ad team eyeing your data.
