The latest smartwatches from Citizen feature an app that utilizes research into alertness and fatigue pulled from NASA plus A.I. models created by IBM Watson Studio to help you better understand the way your body performs each day. The app is called YouQ, and rather than only looking back at how you've performed, it also looks ahead. By tracking your sleep and through custom gamified tests, the YouQ app will work out daily "Power Fixes," which are recommended actions designed to improve alertness and minimize fatigue. The more you use the YouQ app and its actions, the more effectively the app can make recommendations about your day's ideal health activities. There are two new second-generation smartwatch models from Citizen, the CZ Smart Sport and the CZ Smart Casual, with the names giving away the basic style of each one.
