Why parents choose NapKit

Everything here is free, with nothing to set up before your first nap.

One-tap start and stop

Begin or end a sleep session with a single tap. Nothing to fill in while you are holding a baby.

Automatic nap and night detection

NapKit works out whether a session is a nap or a night, and you can override it any time.

Lock Screen Live Activity

The running timer sits on your Lock Screen, so you can stop a sleep without unlocking. Stop it and the card shows how long your baby slept, so you know it was saved.

Home Screen widget

Start and Stop buttons right on the widget, with a row for each baby.

Lock Screen and Control Center buttons

Start or stop sleep from the Lock Screen, Control Center, or the Action button, without opening the app.

Rate every night

Give a night one to five stars and see what your best nights have in common: bedtime, naps, and time awake.

History you can edit

Full sleep history with daily totals. Forgot to hit stop? Fix the entry in a few seconds. Deleted one by mistake? Tap Undo.

It notices a forgotten timer

If a nap runs well past your baby's usual, NapKit asks whether they are still asleep and lets you set the time they woke. Today shows how long they have been up.

Sleep tips for your baby's age

Short, age-based guidance while your baby is awake, from newborn to two years and beyond. General guidance, not medical advice.

Multiple baby profiles

Track more than one child and switch between them instantly.

Works offline

No account and no connection required. Your data lives on your device.

No third-party tracking

Nothing about your baby is sold, shared for marketing, or used for advertising.
