You’re walking. You’re sweating. You’ve been pacing the living room for twenty minutes just to hit that 10,000-step goal, but when you look at your phone, the number hasn’t budged. It’s still sitting at 4,231. It’s frustrating. It feels like the walk didn’t even happen if the digital ticker doesn’t acknowledge it.
Honestly, it’s rarely just "broken." Most of the time, the reason why is my fitness app not counting my steps comes down to a weird conflict between your hardware sensors and how the software interprets movement. Your phone isn't a pedometer from 1995 that uses a physical swinging pendelum. It uses a complex piece of silicon called a triaxial accelerometer. If the software isn't "listening" to that chip, those steps vanish into the digital void.
The "Battery Saver" Trap You’re Probably Falling Into
Modern smartphones are obsessed with staying alive. Both Android and iOS have become incredibly aggressive at killing "background processes" to save juice. If your fitness app—whether it’s MyFitnessPal, Strava, or a proprietary brand app—isn't whitelisted, the operating system might just put it to sleep while it’s in your pocket.
It’s a classic conflict. The app wants to poll the accelerometer every second. The phone wants to shut down the app to save 2% of your battery. On Android, this is usually "Battery Optimization." If you haven't toggled this off specifically for your fitness tracker, the phone will stop the app from "hearing" the motion data the moment the screen goes dark.
Think about the way you carry your device, too. The accelerometer needs to feel the impact of your heel hitting the ground. If you’re pushing a stroller, holding a grocery bag, or keeping your hands in your pockets while wearing tight jeans, the "swing" motion that apps look for might be dampened. It's not just about movement; it's about a specific rhythmic pattern.
Why Your Sensors Might Be "Ghosting" You
Hardware fails. It’s rare, but it happens. However, before assuming the chip is dead, consider the "System Health" of your motion calibration.

On iPhones, there is a specific toggle under Privacy & Security called "Motion & Fitness." If this is toggled off, the app literally doesn't have permission to see the hardware. It’s like trying to watch a movie through a boarded-up window. Sometimes, a software update will flip these permissions back to default. It’s the first thing you should check.
- Go to Settings.
- Hit Privacy.
- Check Motion & Fitness.
- Ensure "Fitness Tracking" is on.
Android is a bit more of a Wild West. Because every manufacturer—Samsung, Google, Xiaomi—skins their software differently, the "Step Counter" sensor can sometimes get stuck. A simple restart actually recalibrates the sensor fusion hub. It sounds like "IT Support 101," but clearing the cache of the specific app often forces it to re-establish a handshake with the Google Fit API or the Samsung Health core.
The Weird Reality of GPS vs. Accelerometer
People get confused here. They think because they walked three miles on a treadmill, the app should know. But if your app is set to "Outdoor Walk" and it’s looking for GPS movement, it’s going to see you standing still. If the GPS doesn't see you moving across a map, and the app is prioritized to trust GPS over the accelerometer, you get zero steps.
On the flip side, indoors, GPS is useless. It bounces off walls (this is called "multipath interference") and might actually "jitter," making it look like you’re pacing back and forth when you’re sitting on the couch. This is why you sometimes wake up with 50 steps you didn't take.
The Multi-Device Chaos Factor

Most ecosystems try to "deduplicate" steps. If your Apple Watch records 500 steps and your iPhone records 450 during the same ten minutes, the Health app doesn't give you 950. It uses an algorithm to guess which device was more accurate and merges them. If the syncing between the watch and the phone is delayed, your app might show a lower number until the "truth" is reconciled in the cloud.
Sometimes the sync just breaks. Garmin Connect, for example, is famous for having server-side hiccups where the steps show up on the watch but won't "push" to the app for hours. In this case, the problem isn't your legs or your phone; it's a server in a data center somewhere that's having a bad day.
Permissions: The Silent Step Killer
We often click "No" to pop-ups because they're annoying. But if you denied "Physical Activity" permissions when you first installed the app, it’s dead in the water.
- Location Access: Some apps won't track anything unless Location is set to "Always." They shouldn't need it for steps, but they use it to validate the movement.
- Background Refresh: If this is off, the app only updates when you have it open on the screen.
- Storage Permissions: Believe it or not, if an app can't write to its own temporary log files because storage is full, it might stop recording data entirely.
Is it Your Case?
This is a weird one. Thick, ruggedized cases—the kind designed to survive a drop from a mountain—can sometimes dampen the vibration signatures the phone uses to identify a "step." If the phone can't distinguish between the vibration of a car engine and the thud of a footstep because the case is absorbing all the kinetic energy, it might filter those movements out as "noise."
Try a "calibration walk." Hold the phone in your hand—no case—and walk 100 steps while counting them in your head. If the app hits 95-105, your sensors are fine, and the issue is likely how you're carrying the phone or the "battery optimization" settings mentioned earlier.

Fixing the "Frozen" Step Count
If you're staring at the screen wondering why is my fitness app not counting my steps, stop walking and try these specific steps. Don't just keep going hoping it'll "catch up."
First, force close the app. Not just swiping away, but going into the app info and hitting "Force Stop." This clears the temporary memory. Next, check for a "Power Saving Mode" on your actual phone. Most phones disable the high-frequency polling of sensors the moment you hit 15% battery. If you’re in low-power mode, your step tracking is going to be garbage.
Update the app. Developers are constantly chasing bugs caused by new OS versions. If you’re running an old version of a fitness app on a brand-new version of Android or iOS, the "API" (the bridge between the app and the sensor) might be broken.
Finally, check the "Account" settings within the app. Sometimes, you’re logged into two different accounts—maybe one via Facebook and one via Email—and the device is sending data to an account you aren't currently looking at. It sounds silly, but in the world of fragmented logins, it’s a common culprit for "missing" data.
Your Immediate Checklist for Recovery
Don't panic. Your hard work isn't "gone," it just wasn't logged. To ensure it doesn't happen on your next trek, do this:
- Disable Battery Optimization: Go to your phone’s "Battery" settings, find your fitness app, and set it to "Unrestricted" or "Don't Optimize."
- Check Motion Permissions: Ensure the app has "Physical Activity" (Android) or "Motion & Fitness" (iOS) permissions set to "Allow."
- Verify the Source: If you use multiple devices (Watch + Phone), go into the "Data Sources" menu in your main health app and make sure the device you actually carry is at the top of the priority list.
- Clear the Cache: On Android, clear the app's cache to remove any corrupted temporary files that might be blocking the data stream.
- Test with a Pedometer App: Download a basic, "no-frills" pedometer app. If that one works but your main fitness app doesn't, the problem is 100% the app's software or settings, not your phone's hardware.
The reality is that these apps are "guessing" based on vibrations. They aren't perfect. But by removing the software hurdles—the battery savers and the permission blocks—you give the sensors the best chance to actually do their job. Keep the phone in a pocket close to your hip for the most accurate vibration readings, and avoid holding it in your hand if you can help it, as arm swings are much harder for the algorithm to "solve" than the consistent jolt of a hip movement.
