Warning: this app cannot measure body temperature by itself and works with a connected thermometer. The Body Temperature Tracking App is the most connected fever monitoring app in the world that enables users to see trends and export reports. This personal & family body temperature logging assistant enables users to record data manually or to automatically capture readings from over 70 supported smart thermometers via Bluetooth, including infrared and digital meters, as well as patches and other wearable temperature monitors. Aside from body temperature, the app can help track medication intake, SpO2, blood pressure, heart and respiration rate. The app can be used for keeping track of fever during an illness, for basal body temperature monitoring, and even for workplace temperature testing. Data can be recorded and viewed in Fahrenheit or Celsius, as well as displayed on graphs. The app has a clean and intuitive interface and works with or without registration. Users decide if they want to keep their health data on their smartphone only, or additionally back it up to MedM Health Cloud (https://health.medm.com). This Body Temperature Tracking App can log the following data types: • Temperature • Note • Medication Intake • SpO2 • Blood Pressure • Heart Rate • Respiration Rate The app is freemium, with the basic functionality available to all users. Premium Members, additionally, can sync select data types with other ecosystems (such as Apple Health and Garmin), share access to their health data with other trusted MedM users (such as family members or caregivers), set up notifications for reminders, thresholds, and goals, as well as receive exclusive offers from MedM partners.

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. Note: CORE provides products and services designed for general fitness and training purposes. For accurate measurement readings during sports, a connection to a heart rate monitor is necessary. CORE products and services are not medical devices, not intended to treat or diagnose any disease, and should not be used as a substitute for professional medical advice, diagnosis or treatment.
