The "トイレ" app is a handy tool for those in urgent need of restroom facilities. Developed by Lion Corporation, this free iPhone application caters to individuals facing sudden bouts of diarrhea, offering a stress-relief solution by guiding users to the nearest toilets in emergencies. The app features an Emergency Button that provides a map displaying potential restroom locations in supermarkets, convenience stores, cafes, hamburger shops, and family restaurants. Users can also contribute by reporting on whether these facilities are willing to lend their restrooms.

The app aims to enhance user experience by offering a user-friendly interface and a more intuitive design, making it easier for individuals to find the nearest available restroom in times of need.
