Question 1

Does the online pedometer work without an app?

Accepted Answer

Yes. This pedometer uses your phone's built-in accelerometer through the browser's DeviceMotion API. Just open this page on a phone with motion sensors, tap Start, and put the phone in your pocket or armband.

Question 2

How does the step counter detect a step?

Accepted Answer

It looks at the combined acceleration magnitude and counts a step whenever it crosses a threshold and bounces back — the same up-down pattern your body makes while walking. Sensitivity can be tuned for different phones.

Question 3

Is my movement data sent to a server?

Accepted Answer

No. Every reading from your accelerometer is processed locally in your browser. Nothing is uploaded, stored or shared.

Question 4

Why does my step count seem off?

Accepted Answer

Sensor accuracy varies by phone. Try the High sensitivity setting if you miss steps, or Low if it over-counts. Carry the phone in a pocket or armband for the most consistent readings.
