Workout tracking
Can I track workouts on an Apple Watch without the Fitness+ App?
I currently have a Fitbit Sense and I’d like to switch to Apple Watch 7, but I don’t want to pay a monthly fee to track my workouts and fitness goals.
You do not necessarily need the Fitness+ app depending on what you mean by "track" workouts. The built-in Fitness and Health apps track workouts. See the 'Check your Activity history' section in:
Use the Activity app on your Apple Watch - Apple Support
Track your trends in the Fitness app - Apple Support
Use the Health app on your iPhone or iPod touch - Apple Support
