WHY THIS ONE

Movement data for people who sit for a living

Desk days disappear into stillness without anyone noticing. A wrist buzz every sedentary stretch — plus honest step counts — makes the invisible hours visible.

The anti-chair alarm
Configurable sedentary reminders vibrate the moment your still-time runs over.
Your day in numbers
Steps, distance, calories and sleep patterns collected automatically.
Calls on your wrist
Caller ID, messages and alarm reminders arrive as discreet vibrations.
Survives real life
IP68 rated against dust and water, with magnetic charging and a silicone strap.

  2. 2

  3. 3

    Wear and forget

    It tracks in the background; the buzz does the coaching.

Before you use it

  • Wellness readings are estimates for habit-building — not medical measurements.
  • Rinse and dry the strap after sweaty sessions.
  • Charge with the supplied magnetic cable only.

A tracker motivates movement; it does not diagnose anything. Health concerns belong with a professional, not a wristband.

BEFORE YOU ORDER

Questions people ask

How does the sedentary reminder work?

Pick an interval in the app; when your wrist logs no meaningful movement for that stretch, the band vibrates until you get up.

Can I shower with it?

IP68 covers splashes, sweat and everyday water contact; hot showers and saunas shorten any tracker’s life.

What languages does the app support?

A wide set including English, German, French, Spanish, Japanese, Korean and Vietnamese.

How does the multi-buy discount work?

It comes off on its own at checkout, with no code to type. Two items anywhere in your basket take 10% off, three take 15%, four take 20%. They do not have to be the same product.

When will it arrive?

Orders are dispatched within 1–2 business days and usually arrive within 7–12 business days after that; tracking is emailed as soon as the parcel leaves. If it is not for you, unused items can be returned within 30 days — email us first for the return address.
