One button. Lock screen. No AI.

Slumbo tracks your baby's sleep with one tap. The timer lives on your lock screen and your Apple Watch. Nothing else gets in the way.

How it works

In and out in three seconds.

Most baby apps want your attention. Slumbo wants you back on the couch.

Tap Sleep. One big button in the middle of the screen. Works in the dark with one thumb.

Lock your phone. The timer keeps running on the lock screen and in the Dynamic Island.

Tap Wake up. Right from the lock screen. The awake timer starts on its own.

Lock screen

"When did she wake up?"

The answer is on your lock screen and in the Dynamic Island: how long she has slept, or how long she has been awake. No unlocking, no opening the app.

Tap Wake up right there when she stirs. Wearing an Apple Watch? The timer shows up on your wrist too.

Coming soon: both phones

Same baby. Same timer.

Partner sync is on its way: your partner will join with a six-digit code, and when one of you taps Sleep, the other phone will know too, lock screen included. Until then Slumbo keeps the log on one phone.

When it arrives, one plan covers both of you. Other apps charge extra for this.

Apple Watch

One tap from your wrist.

Tap Sleep or Wake up on your watch while your hands are full and your phone is in another room. The timer, today's total and when the next nap is due are right there.

It's on your watch face too, as a complication and in the Smart Stack.

Insights

Charts you can read at 3 am.

Each day is a ring: night sleep in blue, naps in light blue. The week view lines the days up from 6 pm to 6 pm so you can see the rhythm form.

No scores. No grades. Just what happened.

The rest, kept simple

Everything else, one tap away.

Left, right or bottle. Slumbo remembers which side is next.

Diapers

Wet, dirty or both. One tap, with undo.

Growth

Weight, length and head size on WHO charts.

Milestones

First smile, first roll, first steps. Tap it when it happens.

Widgets and Apple Watch

The timer on your home screen, your lock screen and your wrist.

Dark mode

Gentle on your eyes during night feeds.

What we left out

No advice from the machines.

You know your baby. Slumbo keeps the record and stays quiet. No predictions, no coaching, no "your baby should".
