BabySensor Relax Twin
Life with twins is full of little moments. The BabySensor Relax Twin makes it easier to keep an eye on both babies, with readings, audio, and video all in one app. Two sensor wristbands connect to the same base station. You gain insight into each baby’s heart rate, oxygen saturation, and skin temperature, along with information about the surrounding environment.
2 sensor wristbands
1 shared base station
1 wall-mounted app
From small signals to a better overview
01 Attach a wristband to each child.
Choose a suitable size and place the sensor against the skin on the wrist or ankle, as shown in the user manual.
02 Let the base station collect readings.
The wristbands transmit data to the base via Bluetooth. The base also monitors sound and room temperature, relaying the information via Wi-Fi or 4G.
03 Monitor both children in the app.
View readings and customize alerts. The camera connects to Wi-Fi, providing HD video, motion detection, and two-way audio.
MEASUREMENT INTERVALS
Pulse: Every 20 seconds - SpO₂, skin temperature, and room temperature: Every 15 minutes
The measurements are updated at fixed intervals. The camera needs WiFi, even when the base station uses 4G. Access to 4G depends on coverage and current subscription.
A solution for both children
Relax Twin combines two sensors with a shared base, a camera, and an app.
2 sensor wristbands.
One for each child. Measures heart rate, oxygen saturation, and skin temperature. Soft wristbands in three sizes ensure a good fit.

1 HD camera.
Video with audio, motion detection, and two-way audio. The camera connects to Wi-Fi and requires a wired power connection.

This is what the parents say
BabySensor Twin gave me peace of mind every night. I recommend it to other twin parents all the time - it was great for us. Especially in the first few months. I hated being away from it.
Laura Morgan
We bought this unit at the London baby show in 2024 for the future arrival of our twins. It’s been a god send. It was by far one of the best purchases we’ve made in the 2 years of being parents to 2 mischievous babies. From its aesthetic to the seamlessness of paring with both babies at the same time and the ease of the app I cannot recommend BabySensor highly enough. The support and customer service during the 2 years has been incredible and unlike any of the big brands we been able to speak to the owner/designer and tech support with no barriers. 10/10 all day long.
