⚠️ Keep this screen ON while walking — the browser pauses step counting when the screen locks or you switch apps. Don't lock your phone during tracking.
Pedometer engine idle. Tap Start to listen to hardware motion. If your device or browser doesn't expose motion sensors, steps won't auto-increase — this is a real hardware limit of the browser, not a bug in the tool.

Step Counter & Motion Sensor Telemetry Guide
The ColdMatrix Step Counter uses your phone's built-in motion sensor (DeviceMotionEvent) to detect the rhythmic acceleration pattern of walking. Tap "Start Tracking" and keep your phone on you — in a pocket or in hand — while you walk.
Browser & permission notes: Motion sensor access requires a secure HTTPS connection, and some browsers ask you to grant motion permission the first time you tap Start. If your browser or device doesn't expose motion data, step counting will stay at zero rather than fake a number — you can still log your day using the Reset/manual approach.
Heart rate: Tap Measure and cover your rear camera and flash with your fingertip — the app reads the color pulse in your blood flow over 15–30 seconds to calculate BPM, the same principle used by camera-based pulse apps. Hold still for the best reading.
Blood pressure: A phone camera cannot measure blood pressure. Use the Log button to record a reading you've taken with a proper BP monitor — the app stores and tracks it for you.
📖 Complete Guide to the Wellness Studio
The ColdMatrix Wellness Studio is a free, all-in-one health companion that runs in your browser. It combines a step counter, heart rate monitor, blood pressure log, water tracker, and weekly performance report — so you can keep an eye on the basics of daily wellness without installing anything.
What Can This Tool Do?
Step Counter: Uses your phone's motion sensor to count real footsteps while you walk.
Exercise Metrics: Automatically converts steps into estimated kilometres and calories burned.
Heart Rate Measurement: Uses your rear camera and flash to detect your pulse from fingertip blood flow.
Blood Pressure Log: Stores manual readings from a proper BP monitor for tracking over time.
Water Tracker: Quick-add buttons for a 250 ml glass or 500 ml bottle, with a live meter toward 2.5 L.
Weekly Report: See your last 7 days, streaks, averages, and completed goals at a glance.
Daily Auto-Reset: A new day starts fresh — yesterday's data is safely stored in your history.
How Accurate Is the Step Counter?
Browser-based step counting is approximate. It reads your phone's accelerometer and detects motion patterns that look like walking. It works best when:
The phone is in a pocket, in your hand, or on an armband (not in a bag).
You walk at a normal pace — running, shuffling, or stomping may under-count or over-count.
The phone is held relatively still — excessive shaking can trigger false steps.
For medical or training-grade accuracy, a dedicated fitness tracker or smartwatch is still the best option. This tool is designed for general daily awareness, not clinical measurement.
Why Does the Screen Need to Stay On?
Browsers deliberately block background access to motion sensors for privacy reasons. That means if your screen locks or you switch apps, step counting pauses. This is a universal browser limitation — every web-based pedometer works this way. The tool includes a Wake Lock helper to keep the screen on while you're actively tracking.

Frequently Asked Questions
Q: Does this tool work without an internet connection? A: Yes — after the first load, everything runs offline.
Q: Is my health data sent anywhere? A: No. All data stays on your device using local browser storage. Nothing is uploaded.
Q: What happens if I close the tab? A: Your steps and daily data are saved. Reopen and continue where you left off — but steps taken while the tab was closed won't be counted.
Q: Can I trust the camera heart rate reading? A: It's a good general estimate, like most phone camera pulse apps. For medical decisions, always use a proper pulse oximeter or consult a doctor.
Q: Can this app measure blood pressure? A: No — no phone camera can measure blood pressure. Use the manual log to store readings from a real BP monitor.
Q: Is this tool really free? A: Yes — 100% free, no signup, no ads that track you, works offline.
