Elvie is a patented exercise tracker designed to strengthen and tone pelvic-floor muscles. Made from the highest quality medical-grade silicone, the device links to an app via Bluetooth, giving biofeedback during exercises. This method is shown to help users improve control and endurance of this muscle group. Elvie has passed rigorous testing, resulting in a distinctly small kegel tracker with an optional cover for a custom fit and a discreet carry case that doubles up as an induction charger.
