The landscape of endless new exercise machines and gadgets make it more complicated than ever to do that which is so essential for basic health. Quantifit is an iOS app to be paired with the (concept) companion jump rope and dumbbells. The complete experience aims to combine the latest technology with simplicity. Using three simple products, you can get a full body workout anywhere, fully tracked and quantified for Apple HealthKit. Classmate Megan Hopps and I imagined what this experience would be like and designed the app to match, validating hypotheses through user research and testing as we went.
