Apple just fixed one of my biggest problems with the Apple Watch Workout app. Before watchOS 3, your exercise stats—heart rate, calories burned, mileage—were displayed on separate screens, so you had to swipe to view them mid-workout. Now the watch displays all of those metrics on one screen by default.
You can change that if you prefer the old way: Just open the iOS Watch app, then tap through My Watch > Workout and select Single Metric. Instead of swiping, you can use the Digital Crown to scroll through each stat. I prefer Multiple Metric, but you do you.
You can even customize which four metrics are displayed for all 12 workouts, if you’d rather see average pace than heart rate on an outdoor run, for instance.
