About
WristMET Calculator — an open-access tool developed to estimate energy expenditure from wrist-worn wearable sensor data. Using accelerometer and gyroscope signals from commercial smartwatches, this calculator applies a machine learning model to generate minute-by-minute metabolic equivalent of task (MET) estimates. Sample data can be obtained from here.
The underlying algorithm was trained and validated in both laboratory and free-living settings, with a focus on inclusive performance across individuals with obesity — a population often underrepresented in wearable energy expenditure models. Compared to widely used actigraphy-based methods, the WristMET Calculator demonstrates improved accuracy and generalizability, particularly for wrist-mounted devices.

Welcome to the WristMET Calculator!
WristMET Calculator — an open-access tool developed to estimate energy expenditure from wrist-worn wearable sensor data. Using accelerometer and gyroscope signals from commercial smartwatches, this calculator applies a machine learning model to generate minute-by-minute metabolic equivalent of task (MET) estimates. Sample data can be obtained from here.
The underlying algorithm was trained and validated in both laboratory and free-living settings, with a focus on inclusive performance across individuals with obesity — a population often underrepresented in wearable energy expenditure models. Compared to widely used actigraphy-based methods, the WristMET Calculator demonstrates improved accuracy and generalizability, particularly for wrist-mounted devices.
This tool is based on the study: Wei et al., "Developing and comparing a new BMI-inclusive energy expenditure algorithm on wrist-worn wearables," Scientific Reports (2025).

The WristMET Calculator was created by the HABits Lab at Northwestern University. We invite researchers to use this tool and contribute to the development of inclusive, transparent models for human activity sensing.
