Steps and distance not consistent with previous days, and gps

[Mterree12]

I have a Fitbit Charge HR, on Friday 10,000 steps was 4.43 miles, on Saturday my Runtastic GPS said that I walked 5.75 miles, and my Fitbit said that I walked 4.5 miles and 10,000 steps, today I've walked 4.95 miles and I have 10,000 steps, the miles match my GPS, but the steps are all over the place. I tried all of the suggested fixes on the Help, but I'm still getting inconsistent results. Any suggestions?

It's nice to see you around @Mterree12, hope you're doing great today ! 

Fitbit trackers 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, the tracker can pick up some extra steps if it thinks you are walking. Many of these situations—such as working or cooking—do include a few steps in-between stationary periods so the tracker 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 wrist-based trackers, its important to specify whether you wear the tracker 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 tracker at the top of the screen.

If you feel that your step count and distance are inaccurate, first make sure the wrist placement settings are correct. You may also want to manually adjust the stride length that we calculated automatically based on your height and gender. For more information, see How do I measure and adjust my stride length?

If after taking these factors into account you still think your tracker is significantly undercounting or overcounting steps, please try a step 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!
