The FlowPad looks like your run-of-the-mill menstrual pad but is built with a microfluidic diagnostic layer underneath that directs menstrual blood into biomarker zones for testing fertility, ovarian health, and perimenopausal hormones. The results of the test show up in Vivoo's app after a user scans the pad's results through their phone camera or enters them manually. The ethos behind FlowPad and Vivoo's smart toilet is simple.
