Overview
The Omron HJ-151 is a hip-clip pedometer using a single-axis accelerometer to count steps, separating regular steps from brisk ones and tracking time and distance. It stores up to 7 days of data and resets automatically at midnight.
This is a basic display-and-memory pedometer rather than a connected fitness tracker, which suits anyone who wants a number without an app account. The four-mode design, splitting regular steps from brisk ones, is a bit more detail than a typical step counter offers.
- Single-axis accelerometer for hip accuracy
- Four modes: steps, brisk steps, time, distance
- Distance and time tracked alongside steps
- Automatic daily reset at midnight
Who it's for
Fits anyone who wants a no-frills step count without pairing a phone or wearing a wrist device. Less suited to people who want GPS, heart rate, or history beyond 7 days.

Performance notes
A single-axis accelerometer mounted at the hip is what separates this from a wrist-worn tracker; it counts steps while distinguishing a regular walking pace from a brisk one. Time and distance are tracked alongside step count across four display modes, and the unit holds a week of history before resetting to zero at midnight.
