Overview
The multifun SM01 is a digital jump rope that pairs a rotation counter with a weight-based calorie estimate, aimed at people tracking reps and rough energy burn during HIIT, boxing or general cardio sessions.
The listing leans heavily on lab-grade sensor language, but the concrete facts are simpler: a 9 foot adjustable cable, dual Hall-effect sensors for counting, a CR2032 battery rated near six months, and a counter that accepts a body-weight input between 100 and 400 lbs to shape its calorie math. The title also flags a separate 2026 OneClip variant for tool-free length swaps, meaning this SM01 version requires cutting the cable to adjust length.
- Dual Hall-effect sensor counting
- 100-400 lb weight input for calorie estimate
- 9 ft adjustable cable
- CR2032 battery rated up to 6 months
Who it's for
Fits anyone who wants a jump rope that also logs jump count, time and an estimated calorie burn without pairing to an app. Not the right pick for someone who wants to change rope length repeatedly without cutting cable, since that feature belongs to a different variant.
Pros and cons
- Built-in counter removes the need for a phone app
- Adjustable target count or time with audible alert
- User-replaceable CR2032 battery
- Anti-slip handles for sweaty sessions
- Length adjustment on this model requires cutting the cable
Performance notes
Dual Hall-effect sensors sample rotation every 0.001 seconds, which the listing says avoids missed or double counts during fast double-unders. The counter can be set to alert at a target jump count or duration with an audible beep, and the CR2032 battery is user-replaceable with an auto-sleep feature to extend its life.
