Cosinuss° One is an application to receive and record heart rate, heart rate variability and body temperature data continuously. These vital signs and additional parameters are shown in real time during your workout and are stored on the smart-phone. You can export all your data in CSV files and use them with any spreadsheet applications as Microsoft Excel or LibreOffice Calc. You can receive and record all three vital signs – using the new °One sensor – or just with another sensor device transmitting via Bluetooth 4.0. Optimize your exercise and listen to the signals of your body! Continued use of GPS running in the background can dramatically decrease battery life.
