iPhone Fitness App Without Apple Watch in iOS 16

Starting with iOS 16, Apple made its standalone Fitness app accessible to all iPhone users, removing the requirement to own an Apple Watch. This guide covers how the standalone Fitness app functions, detailing the metrics it tracks using your iPhone’s internal hardware, which features remain exclusive to the Apple Watch, and how to configure your daily activity goals directly on your device.

The Red Move Ring

When using the Fitness app without an Apple Watch, the standard three-ring interface (Move, Exercise, and Stand) is simplified into a single red Move ring.

  • Active Calories: The Move ring tracks estimated active calories burned throughout the day rather than total resting calories.
  • Goal Customization: You can adjust your daily calorie burn target at any time to match your personal activity level.
  • Absence of Stand and Exercise Rings: Because measuring stand hours and dedicated workout exertion requires continuous wrist-based tracking, the blue Stand and green Exercise rings are hidden entirely.

How Movement Data Is Collected

The iPhone relies on built-in hardware and software integrations to calculate your movement:

  • Motion Coprocessor and Accelerometer: The iPhone's onboard sensors continuously measure steps, distance traveled, and overall movement patterns when the phone is carried in your pocket, hand, or bag.
  • Third-Party App Integration: If you log workouts using compatible fitness apps (such as Strava, Nike Run Club, or Asana Rebel), the data syncs to the Apple Health database. The Fitness app reads this workout data and counts the calories toward closing your Move ring.

Setting Up and Using the App

  1. Open the Fitness App: With iOS 16 or later installed, the Fitness app appears automatically on your Home Screen.
  2. Set Your Profile: Enter your personal metrics—date of birth, sex, height, and weight—to allow the system to estimate calorie expenditure accurately.
  3. Choose a Daily Move Goal: Select a light, moderate, or active calorie target.
  4. View Trends and Activity: As you use the app over time, it generates Activity Trends that compare your recent 90-day progress against the past 365 days across metrics like daily Move burn and walking pace.

Sharing and Competitions

The standalone Fitness app retains the social features found in the full version:

  • Activity Sharing: You can invite friends and family to share Move ring progress, regardless of whether they track activity via an iPhone or an Apple Watch.
  • Notifications: You will receive alerts when sharing partners close their Move ring or achieve milestones.
  • Awards: You earn digital badges for personal records, movement streaks, and special holiday fitness challenges.

Limitations Without an Apple Watch

While the standalone app provides reliable general activity tracking, several features remain unavailable without an Apple Watch:

  • Real-Time Heart Rate Monitoring: The iPhone cannot measure your pulse during workouts.
  • Wrist-Based Workout Tracking: You cannot natively log specialized gym sessions (like weight lifting, swimming, or high-intensity interval training) directly inside the Fitness app without using a third-party companion app.
  • Stand Detection: The phone cannot track hourly standing intervals to prompt you to move.
