2.0 out of 5 stars Great idea, but too unreliable when it actually matters

2026-02-17    -Ali G

The concept is good, and a wearable digital thermometer for babies is exactly what parents need. Unfortunately, this one falls short in real-life use.This device must work at 3 a.m. when your child is crying and you need an accurate temperature fast. In my case, it didn’t. The thermometer kept disconnecting from the app and often would not reconnect, even when the phone was right next to it. Restarting the app and moving closer didn’t help.Battery life is another issue. It dropped to 20% in less than a day, which makes it unreliable for overnight monitoring.Because of the connection problems and poor battery life, I can’t trust this device when it matters most. I’m returning it and will wait to see if a future version fixes these issues.Great idea, but not ready for real-world use yet

**Edit - WOW! Momcozy’s customer service is AMAZING! Adding a star back just for their awesome customer service! They reached out after reading my review and offered a full refund for my inconvenience with the disconnecting issues. They also let me know that they have made updates and new updated version should stay correct these issues! This has gave me so much faith in Momcozy products! I will absolutely be recommending and using them in the future!** This is such a great concept and will be a great product once a few bugs are worked out. My main issue was that the app kept losing connection and having to reconnect every 20 minutes or so. I couldn’t trust that the app would alarm me if his temperature spiked since I looked at the app multiple times and it was disconnected. This wearable thermometer is pretty new and I think once it is around for a while they will air out all the kinks and it will be an incredible product for us moms and dads!

5.0 out of 5 stars Review edited to reflect my own mistake

EDIT: I WAS WRONG!! You can replace the battery.I’m in the trenches with a newborn so I most likely missed this but Momcozy sent me directions clarifying that you CAN replace the battery and how. Thank you guys.Can’t replace batteries so you have to buy another $50 thermometer.This idea is amazing. However, when I was looking for what battery to put into it, you can’t even replace the battery. It’s integrated and you’re unable to replace it. If this is a necessary design result or for them to just make more money, I’m not sure. But this feature should be more upfront in the description.

5.0 out of 5 stars Helpful for short-term use, just keep the battery in mind

As a first-time mom, I got this item hoping it would life a little easier when my son is sick (likely from daycare!) and overall it has. It’s simple to use, easy to “install”, and didn’t feel overwhelming when I’m always already exhausted.For the short time we’ve been using it, it’s done what it’s supposed to do (measure bae’s temp!) and has definitely helped take some pressure off the resistance (I.e., pushing a metal orb across his head = unhappy baby). In the instructions there is a QR code. I really appreciated not having to read a long instruction manual or troubleshoot anything complicated because it’s pretty straight forward/user friendly.The biggest downside is the battery which is on the smaller side, and I did find myself needing to charge it more often than expected. The smallness is a concern because kids eat things and this would be terrible to swallow. However, you can put a tegaderm patch over it to keep it on. That’s what I did and it was fine.I do agree that it does die fast. Once I got into the habit of plugging it in whenever I wasn’t using it, it became much less of an issue. Keeping a charger nearby or charging overnight helped a lot.You do have to download an app that track the thermometer but I’m fine with that. It’s easy to understand and use. Again, fairly user friendly.I’d say this is a good product for short-term use, especially during the newborn stage or for travel. As long as you’re aware of the battery limitations and plan around them, it works well and is worth having. Overall, I’m glad I added it to our setup as a new mom figuring things out, it measures the temperature accurately (so far), and is lightweight.I HIGHLY suggest buying small tegaderm to ensure the sensor stays on and you’re not worried about the battery falling off and baby eating it.

5.0 out of 5 stars BATTERY IS REPLACEABLE

Great peace of mind tool. For anyone that wondering, battery IS replaceable! Just put it in a case and turn top cover counterclockwise. I have no idea why manual does not explain it in detail. Anyways, it’s TUYA based app which is great and reliable. Temperature adjusts almost in real time. Enjoy

The Momcozy Wearable Digital Thermometer has been a game-changer for monitoring my child’s temperature! It’s incredibly convenient—just stick it on, and it continuously tracks temperature without disturbing sleep. The app syncs easily to my phone, giving real-time updates and alerts if the temperature rises.It’s lightweight, comfortable, and gentle on my child’s skin, so they barely notice it. I also appreciate the hygiene factor—single-use stickers make it clean and easy to manage. No more stressful nighttime wake-ups or constantly checking with a traditional thermometer!Pros:• Continuous, real-time temperature monitoring• Comfortable and gentle for infants and toddlers• Easy-to-use app with alerts• Hygienic and convenient single-use stickersCons:• Needs replacement stickers regularly (sold separately)Overall, it’s an excellent investment for parents who want stress-free, accurate temperature monitoring at home or on the go.
