NORA Smart Sock

Day and night.

Everywhere you go.

Heart Rate

Heart rate reading is designed for sleep tracking, sleep training and more general wellness purposes. Heart rate slows down when baby starts to fall into sleep. Reading the heart rate helps the parents to know how shallow or deep the baby is sleeping, which is helpful for sleep tracking and training. For example, parents can put the baby down into crib if its heart rate starts to slow down (in healthy range), which is a good practice of sleep training. An example of general wellness is NORA can detect elevated heart rate (in healthy range) in feeding.

Feeling Temperature

The NORA sensor measures the foot temperature, which is always lower than the body's core temperature. It's a good indicator that the baby is feeling too warm or chills, so you know to put on more or less. It's very useful when the baby is travelling in a vehicle.

Sleep Position

Babies should always sleep on backs. The sensor estimates the baby's sleep position and sends you on-stomach alerts when the baby accidentally rolls over on its stomach or someone gets started holding the baby in arms. The position alert can override iOS or Android settings like the do-not-disturb. The alert is a smart one to avoid false alarms. For example, it requires baby was in deep sleep and suddenly baby was on-stomach. It's not that every time the sensor is flipped it will alert.

Sleep Tracking

The sleep quality gives you an overlook of the baby's sleeping history and pattern. You can easily check how many hours your baby slept. A baby's sleep pattern evolves everyday as it grows everyday. It's very useful when you do a sleep training on your baby since 3-month-old.

NORA Smart Sock

All support 'Diaper Mode'.

Why Diaper Mode?

Supporting the 'Diaper Mode' is very necessary because babies over 6-month-old start to grab and strip socks. The NORA sensor is able to hide in the diaper, draws little attention and allows a much longer use to 3-years-old.

Allow to Learn Skills

Switch to the Diaper Mode, so babies can start to learn skills like pushing feet, crawling, sitting and standing.

Road Trips

Thanks to the NORA's direct wireless link to your smartphone, you can use it anywhere. It does not require WiFi or internet, so you can enjoy road trips and even flights with the NORA keeping an eye on your baby.

Smart Alerts

All critical alerts are smart ones to avoid false alarms. For example, it requires baby was in deep sleep and suddenly baby was on-stomach to trigger on-stomach alert. It's not that every time the sensor is flipped it will alert. Handpicked and authorized by Apple Inc., the iOS APP can post ‘Critical Alerts’ on your iPhone. It overrides the Do-Not-Disturb or Silent-mode. It makes sure your iPhone can produce a sound even in the middle of the night even you put on Do-Not-Disturb on purposely. For Android, please manually allow DND override in settings.

Flexible Alerts

All notifications and alerts in the NORA Sock App can be individually turned on or off, so it fits into your situation without compromise. Heart rate and sleep position are 'critical alerts'. They can override Silent-mode and Do-not-disturb. The overriding can be enabled or disabled in iPhone and Android settings.

Quick Recharging
