OiTr

OiTr is Japan's pioneering Chrome extension that provides free sanitary napkins through private restroom dispensers, ensuring hygienic and convenient access via a smartphone app. Users can dispense napkins without touching the device, thanks to antibacterial-treated dispensers activated by simple app-to-device communication.

Beyond free sanitary products, OiTr empowers users with menstrual cycle prediction, schedule management, and health condition tracking — all accessible through an intuitive app interface. With no initial registration required, the service encourages responsible use with ticket limits and recommended usage intervals to promote safety and well-being. OiTr actively supports women's health by easing access to essential menstrual care and enhancing awareness and management of menstrual health.
