Elvie is a kegel exercise tracker for woman. The company is taking pre-orders for $95.

The pelvic floor is a powerful little set of muscles that sits like a hammock between your tailbone and pubic bone. Kind of hidden, but very important, they lift and hold your core. Like any muscle, with a bit of exercise and effort, you'll feel the benefits. Better core stability, control and even better sex. Elvie's unique technology helps women of all ages and fitness levels achieve their goals.
