How does the step counter work and how can I improve its accuracy?Updated 3 hours ago

👟 How does the step counter work?

Your watch has a motion sensor that measures the movement of your wrist. It estimates your steps from the rhythm of your arm swing while you walk. It does not detect your footsteps directly.

Steps: counted from the movement of your wrist.
Distance: calculated from the number of steps and your step length.

💡 Because the watch measures your wrist and not your legs, its count can differ from a phone or another watch. Two devices rarely show exactly the same number.

⚠️ Why can the count differ from reality?

Fewer steps than you actually took

The watch counts fewer steps when your arm hardly moves, for example when you:

hold your phone, a bag or a coffee in your hand
push a stroller or a shopping cart
hold a handrail or walk with your hand in your pocket

More steps than you actually took

The watch can add steps when your wrist moves without walking, for example when you:

drive or type on a keyboard
cook, do housework or brush your teeth
make hand gestures while talking

Other causes

The watch is worn too loosely.
The step length entered in the app does not match your real step length (this affects the distance).

⚠️ These differences are an expected limit of wrist-based step counting, not a defect. The step count is an estimate and is not a medical measurement.

🧮 How to calculate your step length

Where to enter it

Open the app of your watch and go to the profile information. Check that your height, weight, age and sex are correct, then enter your step length in centimeters (cm).

Estimate it from your height

Men: step length (cm) = height (cm) × 0.415
Women: step length (cm) = height (cm) × 0.413

Examples: a man of 170 cm has a step length of about 70.5 cm (170 × 0.415 = 70.55). A woman of 165 cm has a step length of about 68.1 cm (165 × 0.413 = 68.145).

Measure your real step length

Mark a distance of 10 m.
Walk it at your normal pace and count your steps.
Step length (cm) = 1000 ÷ number of steps.

Example: 14 steps for 10 m gives a step length of about 71.4 cm.

Check the distance

Distance (m) = step length (cm) × number of steps ÷ 100. Example: 70.5 cm × 1000 steps ÷ 100 = 705 m.

💡 The result in centimeters can be entered directly in the app.

✅ How to improve accuracy

Wear the watch well fitted, about one finger width above the wrist bone.
Swing your arms naturally while walking.
Check your profile information and your step length in the app.
Keep the watch connected to the app and synchronize it regularly.

🧪 Test your watch

Test 1: 100 steps

Walk 100 steps, counting them aloud, with a natural arm swing. Compare your count with the number shown by the watch.

Test 2: steps added while you are not moving

Put the watch on a table, completely still, for 10 minutes. Check whether the step count changes.

If steps are still added on the table

Remove the watch in the app.
In your phone's Bluetooth settings, select the watch and choose "Forget this device".
Reset the watch to factory settings from its settings.
Pair the watch again with the app, then repeat Test 2.
