## What is Numsy?

Calmer days. Calmer nights.

Numsy helps you get a better feel for your baby's sleep, without a strict schedule and at your own pace. Warm, practical and made for tired parents. More than 1,000 parents already keep track of their rhythm with Numsy.

WHAT YOU GET

Wake windows and sleep windows that fit your little one
The day circle shows when the next nap is likely due and when bedtime is coming, based on your little one's age and their own rhythm. With the widget you see it right on your home screen.

A simple sleep tracker, in a few taps
Log naps, night sleep, feedings, diapers and night wakings in a few taps, even with your little one in your arms. Forgot one? Add it afterwards.

Numo, your AI sleep coach, and a real coach too
Ask Numo about naps, feeding or the night and get an answer straight away. Numo knows your little one's rhythm. Prefer a person? A human coach is there for personal support.

White noise and calming sounds
White, pink and brown noise, a fan and shushing, with a timer and clear tips on using sounds safely. They keep playing without internet. You can even record your own voice.

Track it together
Link your partner, babysitter or the grandparents with a code. Everyone logs on their own phone and sees the same overview.

Insights that give you something to hold on to
Average naps, a rhythm score, night wakings over time and a gentle weekly recap. No report card, just a clearer picture. Watch the nights get calmer.

Know what's coming, stage by stage
Fewer naps, teething, sleep regressions and leaps, explained in good time and with step-by-step help. Plus a Sleep bootcamp with short lessons.

For every stage
From newborn sleep to toddler, Numsy grows along with your little one.

Numsy offers warm, practical support and general information, not medical advice. When in doubt, check with your pediatrician.

Try it free: the monthly plan starts with 7 days free. There is also a yearly plan. You can cancel anytime, also during the trial week, in your phone settings.

## Version history (last 5 releases)

### 1.1.31 — 2026-10-23

Already added the widget to your home screen? The app now spots it right away and ticks off that step. The sign-up screen is calmer too. Plus small improvements.

### 1.1.30 — 2026-10-22

The widgets on your home screen now use the same icons as the app: nap, night, breast, bottle, diaper and the rest. Numo got the same makeover. Plus small improvements.

### 1.1.29 — 2026-10-21

Starting up on a slow connection: you see the Numsy mark right away, and if loading stalls, the app reloads by itself. Numsy is now available in English, German, Spanish, French and Portuguese. In the app, texts in these languages fit better: buttons and explanations are no longer cut off, and tips about your care provider match the language you use. Plus small improvements for screen readers.

### 1.1.28 — 2026-10-21

Numsy spreekt nu ook Engels, Duits en Spaans in de App Store. In de app zelf kloppen de teksten in die talen beter: knoppen en uitleg worden niet meer afgekapt, en de tips over je zorgverlener passen bij de taal die je gebruikt. Verder kleine verbeteringen voor schermlezers.

### 1.1.27 — 2026-10-20

Het widget denkt nu mee. Loopt er een slaapje, dan staat er Wakker: een tik stopt het slaapje en na een nacht noteert hij meteen dat je kindje wakker is. Daarna staat op dezelfde plek Dutje, voor het volgende slaapje. Het kleine widget Laatste voeding kun je nu aantikken: tik op de voeding om een fles te noteren, tik op het slaapje om het te starten of te stoppen. Geef je flesvoeding, dan staat Borst niet meer op het widget. In Inzicht kies je zelf welke onderdelen in de lijst staan en in welke volgorde, en bovenaan Vandaag zie je hoeveel flesjes, dutjes en luiers het al zijn.
