Meet the D Free: a smart wearable device that detects activity in your intestines and lets you know when you should think about visiting the bathroom. It is designed to give the elderly or folks with bowel dysfunctions ample preparation time to visit the bathroom. The device learns about your lifestyle to give you more accurate notifications.
D Free knows when you will need to visit the bathroom before you even know it and notifies you on your smartphone. You can find out more about it here.
