The concept of a digital women's health category is relatively new.[1][5][6][7][8] Femtech was coined in 2016 by Ida Tin, a Danish entrepreneur who founded Clue, a period- and fertility-tracking app.[5][6][9] As an industry, femtech largely encompasses any digital or standard health tools aimed at women's health, including wearables, internet-connected medical devices, mobile apps, hygiene products, and others.[5][10]
