DFree is a first wearable device to predict when you need to go to the toilet. It is for seniors and people with disability who suffer from loss of bladder control. This wearable device will continuously monitor your bladder and notify when your bladder is almost full so you know when to go resulting in less “accidents.”


Having control of your senses is the key to independence and living your life with confidence and dignity.
