Huge discrepancy in steps compared other watch

[SunsetRunner]

Huge discrepancy in steps compared other watch.  I have Apple Watch three series and have been comparing my steps by the end of the day there is at least a 3000 steps gap meaning my fit bit is 3000 steps behind my Apple Watch. This is normal how am I supposed to calculate steps with such a huge discrepancy? Anyone else have this problem which do you think would be right I’ve done test and they both at the time of the test I was spot on. So somewhere during the day when it’s either getting more steps or the other one is losing a lot of steps.

Welcome to the Fitbit Community @SunsetRunner! If you feel that your step count and distance are inaccurate, first make sure the wrist placement settings are correct. Next, double check that you entered your height correctly. Since we use height to estimate your walking and running stride lengths, you may want to measure and manually adjust these values if your legs are longer or shorter than average. 

Sometimes, when you start walking you may notice that your steps may not update on your device right away. After about 10-15 continuous steps, you'll notice the steps catch up and start updating in real-time with each step you take.

As I've mentioned, it's important to specify whether you wear the device on your dominant or non-dominant wrist:

• The dominant wrist setting decreases the sensitivity of step counting and should reduce any over counting of steps when your body is not moving.
• The non-dominant wrist setting increases the sensitivity of step counting and should reduce any under counting of steps. Non-dominant is the default.

To change your settings, in the Fitbit app go to Account tab and choose your device at the top of the screen.

With wrist-based devices, if you move your body a lot and not your arms (or vice versa), you may see a slight difference in step count than you would see if wearing a clip-based device on your torso. 

Fitbit devices have a finely tuned algorithm for step counting. The algorithm is designed to look for intensity and motion patterns that are most indicative of people walking and running.  When working at a desk, cooking, or doing other arm movements, a device on your wrist can pick up some extra steps if it thinks you're walking. Many of these situations—such as working or cooking—do include a few steps in-between stationary periods so the device tries to give you credit for those steps. For the vast majority of customers, the amount of stray steps accumulated is negligible when compared to the entire day. For a more technical explanation, see How does my device count steps?

On bumpy trails it's possible that your device will register steps but these should be negligible in your overall stats. If you have a device with multisport mode, make sure you choose the Bike exercise before starting your workout. If you're relying on SmartTrack to automatically detect your bike ride, make sure the Outdoor Bike exercise is on. (In the app, tap the exercise title and then tap the gear icon in the top right.) If your device doesn't offer multisport mode or SmartTrack, we recommend logging your bike ride manually to get the best calorie burn estimation. For more information see How do I track my exercise and activities with Fitbit?

If you're doing something like pushing a stroller or shopping cart, your wrist-based device will count your steps but the total may be slightly lower than usual.

Once you've reviewed it, please try this step accuracy test:

1. Put your wrist-based tracker on your wrist or put your clip-on tracker on your hip or torso.
2. Walk 100 steps, making sure to count a step each time one of your feet hits the ground.
3. Pause, then check your tracker to see your step count.

Hope this helps, let me know if ther's anything else I can do for you!
