How does health app calculate steps on iPhone?

how does iphone measure number of steps taken

iPhones count steps using the built-in accelerometer.

Here's a generic explanation:

The explanation of the link sounds nice. However, maps tells me the distance measured doesn’t mate with the distance measured by the iPhone. The step is wrong. I count a particular route to be 16 steps but the app only counts 8. 20 steps are measured as 12-14.

In a private house with three floors, I apparently never leave the main floor. Interesting, as I sleep in a guest room on the top floor.

IMHO, not accurate enough to be a reliable indicator of anything other than you’re alive because you walked somewhere.

Hello there!

So I don't know it for sure, but I think the iPhone uses it's sensors, and advanced algorithms to calculate the health data, like steps, how many stairs you climbed, etc.

Hope this answers your question!
