The PRIVY Voiding Diary app helps people monitor their urinating quickly and simply from the sounds via smartphone, without a urine cup or paper. PRIVY analyzes the recorded sound of you urinating, both volume and time, helping you to understand your own self-voiding patterns and the health of your bladder. By detecting potential symptoms, PRIVY can also help keep you healthy, using patterns from analyzed data to assist in self-diagnosis and early treatment.
