How can I see how many calories I have used against my steps on applewatch
On fitbit my watch shows me how many calories I have burned via any activity which encouraged me to use my calorie counter more.
iPhone 11, iOS 17
If you're doing walking workouts, you can see the calorie estimation for the workout. You can also see how many calories you've expended by looking at the Move Ring on your watch. If you tap on the rings on your watch, you can scroll through and see calories and then steps at the very bottom.
There's also an app I've used called StepsApp that will show you your steps and calories on one screen on your watch. It's a very nice app if you're into counting steps.
