Open the pre-installed Fitness app, enter your health details, and set a daily Move goal to track calories and steps using iPhone motion sensors.
You do not need an Apple Watch to track your daily movement. Since the release of iOS 16, Apple expanded the Fitness app’s capabilities to work exclusively with the iPhone. The sensors inside your phone count your steps, estimate distance, and calculate burned calories based on your movement throughout the day.
If you have an Apple Watch, the app pairs with it to provide deeper metrics like heart rate data and Stand hours. Setting this up correctly takes just a few minutes and turns your device into a capable activity tracker.
Getting Started With The Fitness App
The Fitness app comes pre-installed on every new iPhone. If you previously deleted it to save space, you must redownload it from the App Store before proceeding.
Locating The App And Initial Launch
Most users find the app on the second page of their Home Screen or in the App Library. It features a recognizable icon with three concentric rings (red, green, and blue) or just a red ring if you have never paired a watch.
- Open the Fitness app — Tap the icon to launch the setup screen.
- Tap Continue — Review the welcome screen that explains the basic tracking features.
- Grant permissions — Allow the app to access Motion & Fitness data. This is mandatory for the pedometer features to work.
Entering Your Health Details
Accuracy depends on the data you provide. The app uses algorithms that require your physical stats to estimate calorie burn. If you leave this generic, your Move ring might close too easily or be impossible to complete.
- Input your date of birth — Scroll to select the correct day, month, and year.
- Set your height and weight — Be precise here, as this baseline determines your basal metabolic rate.
- Tap Continue to finish — The app saves this data to the Health app securely.
Quick check: You can update these details later in the Health app if your weight changes. Keeping this current helps the algorithms stay accurate.
Setting Up The Fitness App On Your iPhone Without A Watch
If you do not own an Apple Watch, the interface looks slightly different. You will see a single large Red ring. This is your “Move” ring. It fills up as you burn active calories throughout the day.
Your iPhone measures this by tracking your steps and current activity levels. It distinguishes between a slow walk and a brisk jog based on the accelerometer data. To get credit, you must carry your phone in your pocket or hand while moving; it cannot track you if it sits on a desk.
Establishing Your Daily Move Goal
The app asks you to set a daily calorie target. This is the number of active calories you want to burn. Apple suggests a goal based on your entered weight and age, but you should adjust this based on your lifestyle.
- Lightly Active — Set this between 300 to 500 calories if you have a desk job and take short walks.
- Moderately Active — Aim for 600 to 800 calories if you exercise intentionally or have a job that requires standing.
- Highly Active — Users who train daily or work manual labor jobs often aim for 900+ calories.
Pairing An Apple Watch For Full Tracking
When you pair an Apple Watch, the Fitness app expands to show three rings. This hardware adds heart rate monitoring, which allows the system to detect exercise even if you are not stepping (like cycling or rowing).
Understanding The Three Rings
Move (Red): Shows active calories burned. Unlike the iPhone-only version, the Watch counts calories from movements where your arm swings, even if you aren’t walking.
Exercise (Green): Tracks minutes of brisk activity. To earn credit here, your heart rate must rise to a certain threshold, or your pace must exceed a brisk walk. You need 30 minutes daily to close this ring.
Stand (Blue): Counts hours in which you stood and moved for at least one minute. The standard goal is 12 hours per day.
Customizing Your Activity Goals
You might find the default goals too easy or too hard after a week of use. Changing them is simple and helps keep your motivation high. You can adjust the goals for all three metrics if you use an Apple Watch, or just the Move goal if you use only an iPhone.
- Open the Activity section — Tap the rings on the main summary screen.
- Scroll to the bottom — Look for the button labeled “Change Goals.”
- Adjust the Move goal — Use the plus or minus buttons to change the calorie target.
- Update Exercise and Stand targets — If you have a Watch, you can swipe to adjust these daily requirements as well.
Syncing Third-Party Apps And Data
The Fitness app acts as a central hub. It pulls data from the Health app, which means other workout apps can contribute to your rings. If you use Strava for running or Nike Run Club, you do not need to manually enter that data.
Connection steps:
- Open your third-party app — Go to the settings menu inside the specific workout app (e.g., Strava).
- Find “Applications, Services, or Devices” — Look for an option to connect to Apple Health.
- Enable all categories — Turn on the toggle switches for “Active Energy” and “Workouts.”
Once connected, a workout recorded in another app counts toward your Move and Exercise rings immediately.
Sharing Activity With Friends
Social motivation works well for many users. The Sharing tab lets you see friends’ progress and challenge them to competitions. You see their rings fill up in real-time, and you receive notifications when they finish a workout.
- Tap the Sharing tab — Located at the bottom right of the screen.
- Tap the Invite icon — This looks like a person with a plus sign in the top corner.
- Select contacts — Choose friends who also use an iPhone or Apple Watch.
- Send the invite — Once they accept, their data appears in your feed.
You can hide your activity from specific friends temporarily without removing them if you need a break from the competition. Muting notifications from overly active friends is also an option if their updates become distracting.
Troubleshooting Common Tracking Issues
Sometimes the app fails to count steps or closes rings unexpectedly. A few settings usually resolve these glitches.
Fitness App Not Tracking Steps
If your red ring remains empty despite walking, privacy settings often block the sensors.
- Open iOS Settings — Go to the main settings menu on your iPhone.
- Select Privacy & Security — Tap on Motion & Fitness.
- Toggle Fitness Tracking on — Make sure the switch is green. Also, verify that the Fitness app specifically has permission in the list below the main toggle.
Inaccurate Calorie Counts
If the calorie burn seems way off, check your health profile. An incorrect weight entry drastically skews the math. According to Apple Support, keeping your personal information up to date is the best way to improve measurement accuracy across all activity metrics.
Also, remember that the iPhone-only mode relies on motion. Pushing a grocery cart or stroller keeps your phone stationary in your pocket or bag, which might result in “missed” steps because the phone doesn’t feel the natural hip swing of a walk.
Using Widgets For Quick Checks
You do not need to open the app to check your progress. iOS supports Home Screen and Lock Screen widgets that display your rings at a glance.
- Long press the Home Screen — Wait until the icons jiggle.
- Tap the Plus (+) button — Located in the top left corner.
- Search for Fitness — Select the widget size you prefer (small square or rectangular banner).
- Tap Add Widget — Drag it to your preferred spot on the screen.
The Lock Screen widget is particularly useful for checking steps without unlocking your phone. This helps you stay aware of your activity levels during a busy day without getting distracted by other apps.
Why The Fitness App Matters
Tracking activity provides a clear picture of your sedentary habits. Even without a smartwatch, the iPhone offers enough data to help you make small changes, like taking an extra walk or choosing stairs over elevators. The visual feedback of the “Move” ring creates a psychological loop that encourages consistency.
Start with a manageable goal. Closing the ring should require effort but shouldn’t feel impossible. As you get stronger, increase the number to keep the challenge alive.
