世界のトイレ人口

Overview

A simple and clean web app that shares the status of app users who have pressed "I'm in the restroom now." It connects your personal time, just a little bit, with the world.

※ The number of people displayed is the number of users currently set as using the restroom in this app. This is not a statistic that investigates or estimates the actual number of restroom users.

• Elapsed time and remaining time display — State is restored even after reloading or leaving
• Today's record — Number of times and total duration saved in the browser
• A touch of playfulness — Toilet paper increases depending on the number of people
• Accessibility support — Mobile-first, light/dark mode, keyboard operation, screen reader support, and reduced motion settings
• PWA support — Add to home screen and use like an app
• Privacy-focused — No registration of name or email address required. Location API is not used
