Pedometer for your phone: steps, distance and calories
An online pedometer that counts steps with your phone's motion sensor while the page is open. The step counter keeps the screen on, works in your hand or pocket and shows distance, cadence, walking time and progress toward a daily goal; past days stay in a 7-day log.
How to use
On iPhone, allow access to motion when Safari asks. The screen will stay on.
In your hand or in a pocket; for a pocket, turn on pocket mode. Counting begins after the first 7 steps.
The walk goes into today's total and the 7-day log. If you know the distance, recalculate the step length.
Press Start, put the phone in your pocket and walk
Hold the phone in your hand or put it in a pocket. The screen stays on: a browser lets only an open page read the motion sensor.
- Pocket mode: a black screen with no buttons
- Counting starts after 7 steady steps

How counting works
The phone's accelerometer reports motion dozens of times a second. The tool looks for the rhythm of steps in it and starts counting once 7 steps in a row come at an even pace — then adds those 7 too. A wave of the hand, putting the phone down or a bumpy road do not have such a rhythm.
Why the screen stays on
A browser gives the motion sensor only to a page that is open and visible. If the screen turns off or you switch to another app, counting pauses, and the tool shows how long the gap was. In a pocket, use pocket mode: a black screen ignores touches and uses less battery on phones with OLED screens.
Accuracy
In a hand or a pocket the count is usually within a few percent. Distance is steps times step length: enter your height or calibrate on a route you know. Calories are an estimate from speed and weight, not a measurement.
