DFree uses ultrasound to monitor how much urine is in your bladder in real time. Sensor needs to be placed about 0.5" above the pubis bone in order to detect the bladder properly.
DFree uses safe and non-invasive ultrasound technology. Ultrasound technology is also used for prenatal checkups as well as other non-medical devices such as toothbrushes so rest assured that it's safe to use.
DFree sends alerts to your phone or tablet when it is time to go to the bathroom. Set notification threshold to determine when you want to receive notification. Set notification so you have ample time to go.
Your bladder will expand as you accumulate urine and contract when you urinate. DFree uses ultrasound to measure the size of your bladder and indicates how full it is on a scale of 1-10.
