What TempWatch does
Blue light = warm & safe
A steady blue glow means your baby's temperature is normal. No need to check a thermometer every hour.
Red light + beep = cold alert
When temperature drops to a concerning level, the bracelet flashes red and beeps loudly — waking you immediately.
No phone or app needed
Completely standalone. No Bluetooth, no Wi-Fi. The bracelet itself is the alert.
Why we built the TempWatch
Low temperature (hypothermia) is one of the most common reasons a doctor hospitalizes a newborn — for every 1 °C (2 °F) drop in body temperature, a baby’s risk of injury or death increases by 80%. It happens easily, too: small babies lose heat fast, can’t generate warmth or shiver like adults, and low temperature can even be a sign of low blood sugar or infection. And it’s hard to prevent — the consequences begin when a baby’s temperature drops just 1 °F, which can happen even when the baby is wrapped or while parents are asleep. That’s why BEMPU built the TempWatch: to watch over your baby’s temperature continuously, so you’re alerted the moment it matters.
What is TempWatch?
A quick overview for parents — what it does, how it works, and why it matters.
How it works
Blue light means your baby is warm
Slide the soft bracelet onto baby's wrist. A blue light confirms their temperature is normal — no thermometer needed.
Orange light + beeping means baby is cold
If baby's temperature drops, the bracelet flashes orange and beeps loudly to alert you immediately — day or night.
Warm with kangaroo care until the light returns to blue
Hold baby skin-to-skin against your chest. The bracelet will return to a blue light once baby is warm again.

What BEMPU Parents Say
Divya — TempWatch parent
Vineet Joseph — TempWatch parent
“I gifted it to a friend and the new parents were so happy. It beeps whenever the baby is cold. One night it was beeping and woke the mom up — she felt her baby's hands and feet and took her temperature to confirm she was cold. She's so glad she had the watch.”
— Darshan Keshrani, verified Amazon buyer
“Really useful device. It will beep anytime my baby is cold. I felt a lot more comfortable knowing it was monitoring her.”
— Amazon Customer, verified Amazon buyer
“I am so glad I got this product — it's a lifesaver. It alarms when the baby is cold and within seconds we are able to know. Especially helpful for a premature baby.”
— Bharat Sharma, verified Amazon buyer
“I bought these for my twin babies and it worked wonderfully — they beep immediately once the body temperature goes down. Very good quality and value for money.”
— Manoj Chainani, verified Amazon buyer
For Clinicians
Backed by clinical research
TempWatch has been evaluated in 15+ peer-reviewed studies across India, Africa, and globally.
Across these studies, the findings tell a consistent story: newborns — even healthy, full-term ones — become hypothermic more often than expected, and continuous monitoring catches it early enough to act. Babies who wore TempWatch received more kangaroo mother care, gained weight faster, and in one community study had lower mortality four weeks after discharge than babies who didn’t. Health workers and mothers across every study rated the device easy to use and trust, even without a smartphone or reliable electricity.

Frequently asked questions
How does TempWatch differ from a regular thermometer?
A thermometer gives you a reading when you check — TempWatch monitors continuously and alerts you proactively. You don't have to check; it checks for you.
Is it safe for newborns to wear on the wrist?
Yes. TempWatch is CE Approved and ISO 13485 certified. It is designed specifically for newborn wrists and uses a gentle, soft band.
What temperature triggers the alert?
The alert triggers at the clinical threshold for neonatal hypothermia. The exact threshold is calibrated to WHO guidelines for newborn temperature monitoring.
Does it need charging?
Yes. TempWatch has a rechargeable battery. Charge time and battery life details are included in the product manual.
Is TempWatch suitable for clinical and low-resource settings?
Yes. TempWatch is used in NICUs, kangaroo mother care wards, and community health programs. It requires no smartphone and only periodic recharging, making it well suited to facilities with limited electricity. Bulk pricing is available for institutional and government procurement.
Why is hypothermia dangerous for newborns?
Newborns lose heat rapidly and cannot regulate temperature like adults. Hypothermia can cause feeding problems, infections, and in severe cases, death. Early detection is critical.
Your baby's warmth, monitored all night.
