The Apple Watch can track workouts like running, cycling, lap swimming, and high-intensity interval training. It also has guided meditation built in, and activity rings that track how much you move, exercise, and stand.
The Galaxy Watch has 39 built-in workouts, and can automatically track six of them. Like the Apple Watch, the Galaxy Watch also has guided meditation and breathing exercises, but it can also track your sleep cycle and calorie count.
Both the Galaxy Watch and Apple Watch are waterproof and can be worn while swimming.
