Fitbit devices that count floors have an altimeter sensor that detects when you go up in elevation.
Fitbit floors climbed driving.
Your device uses changes in barometric pressure combined with the steps you take to calculate floors climbed.
You can manually log driving as an activity for the times ur on the bus and that should elimate the floors climbed bus also the steps you took so keep this in mind.
Your device registers 1 floor when you climb about 10 feet or 3 meters.
Your device registers one floor when you climb about 10 feet at one time.
Which may mean who knows that it subtracts floors for decreasing air pressure driving downhill.
The fitbit may approximate floors climbed if you actually literally climbed real stairs.
Fitbit devices that count floors have an altimeter sensor that can detect when you re going up or down in elevation.
I also took the quiz to be matched with a product selecting floors climbed as my only desired feature and fitbit matched me to the inspire and inspire hr.
Second it cannot count floors climbed on a stair stepper or a ramped up treadmill because there is no change in air pressure on these machines.
Erince if you manually log driving in your activity log floors and stairs climbed will be negated.
Let me know if you have any additional questions.
