One of the biggest friction points in building any tracking habit is the manual effort and intention required, and FERN by forEVA is a first-of-its-kind smart toothbrush for women that adds hormonal and biometric analysis into a familiar, twice-daily task. This innovation out of Yale Ventures taps into the power of saliva to reveal insights about the female body, and it gets its name from the “ferning” pattern that can be observed under a microscope when salt levels in saliva crystallize through ovulation and hormonal changes. With FERN by forEVA, women stand to benefit from a better understanding of their base operating system, and where they are in their cycle, and what they need in the moment.
For privacy and control, FERN by forEVA sets itself apart with a local device storage option and a voluntary, opt-in subscription plan for an encrypted app that allows data integration with other mobile health tech devices.
