Problem Statement

Have you ever found yourself in a situation where you needed to find the nearest restroom?I certainly have, and I am not alone. According to a study done by the American Crohns Foundation, over 53% of respondents experienced trouble locating the nearest restroom in the last 7 days. Even worse, over 20% experienced a bowel accident, which can completely ruin your day. This was especially relevant for me as I was traveling in a foreign country, didn’t know the language and signage, and eating foreign street food, and ended up having a few close calls.That’s why I am so excited to introduce Hydrofy!
