FAQ - Does the CORE sensor measure when disconnected?

< Back to CORE FAQ

When you are wearing the CORE sensor, it will continue to record. 

The CORE sensor has an internal memory which stores data, even when disconnected from the CORE App for Android or iOS. The next time you start your app and connect, the App will synchronise and load the metrics.

If you are using the CORE sensor with a paired devices cycle computer or watch, the CORE must remain within range to record the core body temperature metrics to the FIT file. In the rare case that the signal to the CORE sensor is temporarily lost, the device will not display the real-time values and the FIT file will have missing data.
