The CORE Thermal Sensor accurately measures your core body temperature and thermal strain on your body – continuously and non-invasively. Thermal data and insights are critical for facilitating safe and effective heat training and for performing optimally on race day. Designed for athletes at all levels, CORE will help to improve your training and performance in your personal adventures or races.
IMPORTANT: The CORE app is designed to work with the CORE device which you can order at www.corebodytemp.com
Here's how it works:
• Set up your CORE sensor: connect your heart rate monitor and sports devices for optimal sensor use.
• Measure your thermal vitals during training: mount the newly designed clip on your heart rate strap and snap in the CORE sensor. Shake the sensor to wake it up, wear it and track your thermal data.
• Core body temperature: the interior temperature deep in your body, including organs and other tissues. A critical measure during sports, it can reach up to 40°C (104°F) during vigorous activity in hot environments. Be aware that hotter is not better – cooler is faster.
• Heat Strain Index: A combination of your core body temperature and skin temperature representing the thermal strain on your body. The real-time feedback on how hard your body is working to stay cool, delivering a value from 0 (no heat strain) to around 10 (extremely high heat strain).
• Heat Zones: Your Heat Strain Index divided into easy-to-use zones. Heat Zone 3 will likely lead to a performance loss, BUT it is the needed stimuli to create adaptations in your body. During heat training, strive for time in heat zone 3. During racing, stay cool and prevent a performance loss by staying in heat zone 1 or 2.
• Heat Training Load: a cumulative daily metric of the heat strain on your body. A daily value of 10 out of 10 indicates ideal contribution to heat adaptations. More is not always better!
• Heat Adaptation Score: Track your heat adaptations over time with effective heat training. Get a heat champion to perform best in the heat. Long-term heat training will most likely lead to improvements also in cool conditions.
• Add your passive heat training: Supplementing your active heat training or general training with passive heat exposure in a sauna or hot bath. You can track your sessions in the app manually, contributing to your heat adaptation score. NOTE: do NOT take your CORE sensor into the sauna or hot environments.
What else you can do in the CORE app:
• Dig into the details: See a breakdown of your thermal data, and even see trends across days, weeks and months.
• Share your CORE metrics with your friends through the social sharing feature, earning more kudos and likes
• Connect your connectivity accounts (e.g. Garmin) to directly synchronize your data after the training.
• Update your sensor to the latest firmware ensuring having the best sensor functionality.

This is an update (and upgrade) of an earlier review. I’ve had this device for 2+ years. It works okay for getting core body temp read in to Garmin Connect, albeit with relatively little guidance on how to really use the data. Routinely, I experience difficulty getting the app to read history data from the sensor. It connects, claims to be getting current data—occasionally toggling to the ‘getting historical data’ message—but won’t show the data. Garmin Connect sees the data immediately after completion of the run or ride, but the CORE app doesn’t. Then usually the data will show up in the app a few days later. It feels like the connection should be faster and more robust; also there should be better diagnostic message of what’s going on. I appreciate that the device needs to be parsimonious with battery life, but the Android/iOS apps don’t need to be.

Thank you for your honest feedback. We would very much like to understand the root cause of the problems you are facing with the CORE app. We kindly invite you to contact us on www.corebodytemp.com to get the problems sorted.
Device works well - connects to my Wahoo device. App adequate.

The device itself works well and certainly gives a pretty good/accurate idea of body core body temperature. I bike in western Colorado - hot and dry in summer and great climbs. I can see where my body temperature is climbing - hot - and what it settles down to when not climbing. Useful i am better at hydrating using this device. I can see my body temperature on my Wahoo unit (the Wahoo unit automatically converts to degrees Fahrenheit) while biking (along with speed, heart rate, watts power, cadence, and when I am using a Supersapiens patch, blood glucose). The app is ok. It has a section to customize whether you want to see temperature readings in degrees centigrade or fahrenheit but I have never been able to make it change. That the Wahoo unit does that makes it nice for when I am actually raising body temperature. The device is good the app adequate - if you like to keep track of your numbers this is another somewhat magical device to give you body temperature reading.
Great start, needs to continue progression.

The app could use some work for ease of use. The data is a little difficult for the non sports pro to understand. Despite not being for medical use, I am using the device to monitor body temperature to see how well my body is regulating temperature since some illnesses cause difficulty with body temp regulation. For that reason, many of the biometrics are of little to no use since I’m not training, but monitoring. My biggest issue is that I cannot sync data with Apple Health—only with my Apple Watch. Additionally, my iWatch has a heart monitor, and I keep it set to continuously monitor, the Core device does not recognize that device data. I am, however, really, really pleased with the temperature monitoring and the device—but would love to see some other functions and compatibility introduced in the app.
Won’t change from Celsius to Fahrenheit

App works ok, wish that there was more information about how to use the device in the app, and that you could export a record of your temperature. But the fact that there is an option in the settings to change from Celsius to Fahrenheit and that the option does nothing is oddly upsetting. Wish it worked.
• Added option to delete passive Heat Training Load entries.
• Other small bugfixes and improvements.
