CORE Thermal Sensor

About this app

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.

Ratings and reviews

Great product, bad app. To get the sensor to sync data, you have to close and reopen the app multiple times, and it will not stay connected. Even worse, it often simply won't calculate a heat training load even when it's showing you spent significant time in heat zone 3. It's useless for tracking progress and useless for safety/monitoring during training. I will probably return the sensor because the app itself is absolute garbage. What a waste of money

I just got the new core sensor 2 and paired it with the app. Very easy to set up in the app. I also connected my heart rate monitor to the app and no issues as well. Then I set the sensor up with my garmin cycling computer and did a session indoors with controlled temperature. reaching the desired heat index. When I finished my session, I opened the app back up, took a couple of seconds for the sensor to connect and then it updated my profile with how the session went. Worked great for me!

It simply never works. Doesn't matter which phone or android version I use. I have used the sensor now nonstop for over 4 years and I need to forget and reconnect the device every single day in my Bluetooth settings. but this is no guarantee that you will see your data (luckily Garmin keeps recording them). I hope this will change with the core 2!
