Overview
A clip-on step counter with a 3-axis motion sensor, large LCD display, and no app or Bluetooth setup required. Includes a removable belt clip and neck lanyard.
This is a bare-bones mechanical step counter rather than a fitness tracker, aimed at people who just want a number at the end of the day without syncing anything to a phone. The tri-axis sensor is meant to count steps whether it's clipped to a waistband or carried in a bag, and the single reset button keeps the interface simple for seniors or kids. There's no heart rate, GPS, or app history here, so anyone wanting workout data beyond a step count should look elsewhere.
- 3-axis sensor, no app or Bluetooth needed
- Large LCD display
- Removable clip plus lanyard
- CR2032 battery rated about one year
Who it's for
Users who want a simple daily step count without an app, phone pairing, or subscription, including seniors and kids who benefit from a one-button interface. Not for anyone who wants heart rate, GPS, or workout history synced to a phone.
Strengths and trade-offs
Drawn from this product's published specifications.

- Large LCD display and single reset button
- No distance, heart rate, or app-based data
- No owner reviews to confirm counting accuracy
Performance notes
The tri-axis sensor is designed to register steps regardless of orientation, so it should count whether it's clipped to a belt, carried in a pocket, or placed in a bag. The device sleeps automatically when not moving and wakes when motion resumes, and a single button clears the count for the next day. A CR2032 battery is rated to last around a year under normal use.
