World’s first toilet timing predicting device

We make and sell world’s first toilet timing wearable device called “DFree”. DFree uses ultrasound sensor to detect the changes of the size of the bladder and predicts the timing of urination. The data collected by the ultrasound sensor are sent to cloud server where we analyze it with our patented algorithm and sends alerts to your smart devices through our application when it is recommended to go to the toilet. With DFree, we can make nursing care more efficient in both time and money wise and also help gain their humanity.
