Joii’s innovation, which is registered as a Class I medical device in the UK, is bringing data to an area of women’s health that has long been ignored and minimised. 

The numbers tell a sobering story. One in three people with periods experience heavy menstrual bleeding. Yet diagnosis can take years. Nearly half of endometriosis sufferers visit their GP 10 or more times before being diagnosed, with 78% reporting they were told they were making a “fuss about nothing. Many women with adenomyosis, fibroids, PCOS and other menstrual health conditions describe feeling similarly dismissed or not taken seriously when seeking help.  

Using sophisticated AI technology paired with Joii’s specially designed pads, Joii’s Period Evaluation app instantly measures blood volume and clot size with clinical precision. Users simply scan their pad with their phone, eliminating guesswork and providing hard data that can be reviewed by clinicians.
