Step Counter (Estimate)
Count steps with your phone's motion sensor while this page is open. Counting stops when the page closes.
This browser does not provide device motion events (DeviceMotionEvent).
Steps are estimated from the accelerometer while this page is open, using a simple peak detector. Walking style, where the phone is carried, and the device itself all change the result — it can easily differ from a dedicated pedometer or fitness tracker by a wide margin. It is not a medical or fitness device, and counting stops when the page closes.
How to use
- Open this page on your phone, press Start counting and allow motion sensor access.
- Walk with the page open; steps are estimated from the accelerometer.
- Set your step length to also see an estimated distance. Counting stops when the page closes.
Notes
Steps are estimated with a simple peak detector over the acceleration magnitude (a dynamic threshold plus a 300 ms refractory period). Walking style, how the phone is carried (hand, pocket, bag) and the device model all change the result substantially, and it will not match a dedicated pedometer or fitness tracker. It is an estimate, not a medical or fitness device. Only the daily total number is stored; no motion data is recorded or sent anywhere.
FAQ
- Does it keep counting with the screen off?
- No. A browser page cannot keep reading sensors in the background, and on many phones the events stop entirely when the screen locks. There is no way for a web page to work around that.
- Will it count steps in a car or train?
- It can: some vibration patterns look like steps to a simple detector. Pause it while riding in a vehicle.
