kGoal is designed to fit a wide range of body types and anatomies. Smartphone Compatibility Note: kGoal is compatible with both iOS and Android devices but does require Bluetooth 4.0 capability and iOS v8 or Android v4.3 or newer as the operating system. Features: Real time, tactile biofeedback: pelvic floor muscles are often controlled subconsciously, and studies have shown that over 30% of women are not able to correctly contract their pelvic floor muscles without direct feedback. kGoal's ability to provide real time feedback via touch and sight can help you make sure you're doing the exercises correctly. Minna's team of experts helped develop algorithms to suggest exercise plans that are tailored to you and based on your current capabilities. kGoal can measure and keep track of things such as muscle strength, endurance, and which exercises you did and when you did them.
