Tension Session
Apple Watch-First Gym App
Free
Tension Session is the best app for planning and tracking your workouts. It's different from competing apps because it is designed to look good and feel delightful to use, adding a little more joy to your training sessions.
Use the iPhone app to plan your workouts. Then, use the Apple Watch app while training to track details and record heart rate data (viewable in the Fitness app on iPhone). Syncing has been designed to be so seamless you'll forget it even happens.
The backend is open source at https://github.com/kevinbevin64/TensionSessionFoundation.
