The body is constantly communicating, and while it's not always easy to notice these signals, technology can play a part in understanding and responding to what's happening with clarity, and Joii is a first-of-its-kind app that measures menstrual insights with AI.
With Joii's specially designed pads and the Period Evaluation app, users benefit from being able to instantly measure blood volume and clot size. “Measuring blood loss is the next logical step in digital health, turning subjective reporting into measurable, clinically relevant data," said Justyna Strzeszynska. "Joii is exploring integration pathways within NHS primary care to support early identification and management of heavy menstrual bleeding.”
In the UK, Joii is a registered Class I Medical Device.
