Posometer is a tool that helps people measure their physical activity in real time. It has been developed by the University of Cambridge and uses a small device worn on the wrist or clipped to clothing. It measures the number of steps taken, distance travelled and calories burned, and it can also be used to set goals and track progress. The device is simple to use and is becoming increasingly popular with fitness enthusiasts. It is also being used in research studies to help scientists learn more about how physical activity affects health and wellbeing. Posometer is an excellent way to monitor physical activity and achieve fitness goals.
