Built for the 3am version of you
Actually get through sleep training
Pick a method, follow a day-by-day plan, and answer one short check-in each morning. NapNap tracks the progress so you can see it working, even on the hard nights.
One tap to start a nap
Timers for naps and night sleep, and predictions that get sharper the more you log.
Never guess “when did she last eat?”
Bottle, breast and solids in one log. Breastfeeding timer with left/right tracking.
See where your baby lands
Weight, height and head circumference plotted against WHO percentile curves.
Diapers logged in two taps
Quick-log every change with type tracking, then see the daily pattern at a glance.
Predictions that learn your baby
Nap and bedtime forecasts from your baby's own wake windows — not a generic age chart.
Both parents, always in sync
Start a timer on one phone, watch it appear on the other. Whoever's on duty sees the latest.
Set up before the next nap
Open the app
iOS and Android. No account needed to start — 30 days of full access, free.
Add your baby's birthday
That's the whole setup. Predictions start from age-appropriate wake windows straight away.
Tap once per nap
Within a few days the predictions switch from age averages to your baby's real rhythm.
What better nights look like
Predictions that stop being averages
The first prediction uses age-typical wake windows. After a few days of logging, NapNap switches to your baby’s own — measured separately for the first nap, the middle of the day, and the stretch before bed. See the wake window chart.
One timeline, two phones
A sleep timer started on one parent’s phone shows up running on the other’s, without a refresh. Both phones write to the same history.
Nothing waits for signal
Every entry is written to your phone first and syncs when there is a connection — a 3am feed logged in a basement nursery is never lost.
Why parents pick NapNap
- Works with no signal. Everything is stored on your phone and syncs later — log a 3am feed in a basement nursery.
- No account required. Skip the sign-up and start tracking. Create an account later if you want sync.
- Two parents, one timeline. Separate phones, same live data — including a running sleep timer.
- 22 languages. Including Romanian, Spanish, German, Polish, Turkish and Korean.
- Switching trackers? Import your history from another app — free, even without NapNap Pro. Delete your account and data any time.
