Human Codex on your wrist: • Your Health Score and today's vitals, one raise away. The watch reads what your iPhone already knows — there's nothing to set up on it. • Train without your phone: your whole training week lives on the watch. Open any day, log every set, pause when you need to, and let the rest timer tap you when it's time to go again. • Fasting from the wrist: start or end a fast on the watch and your iPhone stays in sync. • Your score on your watch face: add a Human Codex complication and it's there every time you check the time. • Weight now flows both ways with Apple Health, with a one-tap sync in Weight History.
