In the morning, you can transfer the previous night’s data from the GrindCare device to the app. To do so, please refer to the instruction manual of BUTLER GrindCare device and open the app to establish a connection. The data will be automatically transferred, and you will be able to browse the app at your convenience during the day.

The bars indicate when and how often the GrindCare device detected grinding or clenching; the number on the top right indicates the total number of detected grinds or clenches for this particular night. Using the diary function, you can select a smiley emoticon corresponding to how you felt upon waking up.
