When a routine doctor visit for heavy periods led to an anaemia diagnosis, Justyna Strzeszynska realised how little objective data exists around menstrual health.
There was no reliable way to measure blood volume or categorise clots — and no language to describe what “normal” really meant.
Her frustration became the seed for Joii, an award-winning fem-tech app and medical-grade tool that helps users measure their menstrual blood loss, track changes, and recognise their period as the 5th vital sign in both reproductive and general health.
In this conversation with Helena Tubridy, Justyna shares:
✨ Her journey from personal experience to health-tech entrepreneur
✨ Why those with endo, adeno, PCOS and fibroids need better menstrual data
✨ How Joii’s discreet scanning technology works — using specially designed pads
✨ How user data is shaping new research into the big question: “What is a normal period?”
✨ And why empowering women with measurable data changes everything
If you’ve ever been told your period is “just heavy,” this episode will open your eyes to the power of real insight — and why menstrual health deserves medical precision, not guesswork.
