A Deeper Signal, Straight from Your Core
Skin temperature reflects the surface, core body temperature reveals the heat trend within. By combining heat-flux sensing, skin temperature, and physiological modeling, Speediance Strap adds deeper context to how your body responds to training, heat, recovery, and sleep.
*Developed by Swiss thermal sensing company greenteg's Calera® core body temperature technology.
Warm-Up Readiness
Sweating does not always mean your body is prepared for higher output. Follow your temperature response to understand when to continue warming up or progress.
Heat Load Monitoring
Feeling hotter does not always mean you are training better. See when heat load is rising and when it may be appropriate to adjust pace, recovery, or hydration.

Frequently Asked Questions
Learn more about the Speediance Strap, the display-free fitness tracker, and its features for your everyday life and training.
What is a fitness tracker without a display?
A display-free fitness tracker records your body and activity data without you having to constantly look at a screen throughout the day. The Speediance Strap works in the background and records heart rate, sleep, recovery, activity, and other health data, among others. You can then view the collected data and personal insights in the Speediance app.
How does the Speediance Strap work as a fitness tracker?
The Speediance Strap uses various sensors to continuously collect body and movement data. These include an optical PPG sensor, a 6-axis motion sensor, and—on the Pro model—an EDA sensor. The data is analyzed in the Speediance app and processed into personalized insights for training, recovery, and well-being.
What health data can the Speediance Strap collect?
The Speediance Strap can collect various health and activity data. This includes, among others, heart rate, heart rate variability (HRV), respiratory rate, blood oxygen, skin temperature, sleep, stress, daily steps, calorie expenditure, and training load. The Speediance Strap also monitors core body temperature trends during exercise.
Can the Speediance Strap monitor core body temperature?
Yes. Speediance is partnering with greenteg, a Swiss thermal sensor technology company. The Speediance Strap uses greenteg's Calera® technology, which combines heat flux and skin temperature sensors with machine learning algorithms to calculate core body temperature.
Do I need a smartphone or a subscription for the Speediance Strap?
To use the Speediance Strap, the Speediance app on a compatible smartphone is required. The Strap is compatible with iOS 13.0 or later and Android 9.0 or later. A mandatory paid subscription is not required to use the core features. Wellness Go is included for the first year with the purchase of the Speediance Strap. After that, you can decide for yourself whether you want to continue.
Is the Speediance strap waterproof and suitable for sports?
Yes. The Speediance Strap is a water-resistant wearable with a 5 ATM water resistance rating, so it can also be worn during workouts. This makes it suitable for everyday use and various sports activities.
How long does the Speediance Strap battery last?
The Speediance Strap fitness tracker offers a typical battery life of up to 14 days*. For the Pro model, the battery life with continuous EDA measurement enabled is approximately 11 days. Charging is done via a USB-C powered magnetic wireless charging station and takes approximately 90 minutes.
* Based on typical usage with 30 minutes of exercise per day. Actual battery life may vary depending on temperature and humidity.
