cosinuss° One





With the earconnect technology developed by cosinuss°, heart rate and heart rate variability are captured extremely accurately using the new circummission-method; body temperature is measured with a very sensitive thermosresistance element. Calculations of the vital signs are achieved with advanced learning algorithms that were developed and aligned for in-ear measurements. Values are then digitalized and transmitted via standardized transmission protocols to smartphones, smart- and sportswatches or other devices.

The Cosinuss° One app

With the brandnew app from cosinuss°, you not only can track your heart rate and the other usual parameters but also your body temperature. Get new and deeper insights into your performance and know when you should not exercise!

Another key feature of the cosinuss° One app is its ability to make over the air updates to your cosinuss° One device so that your device can stay up to date to the newest features!
