How does a running app know if you are walking or running?
Running apps use a variety of sensors in your smartphone to track your movement. These sensors include the accelerometer, gyroscope, and GPS.
The accelerometer measures changes in acceleration. When you walk, your phone's accelerometer detects the up-and-down motion of your steps. When you run, your phone's accelerometer detects the forward-and-back motion of your strides.
The gyroscope measures changes in angular velocity. When you walk, your phone's gyroscope detects the rotation of your arm as you swing it forward and back. When you run, your phone's gyroscope detects the rotation of your entire body as you stride forward.
The GPS tracks your location. When you walk, your phone's GPS can track the distance you travel and the speed at which you move. When you run, your phone's GPS can track your location more accurately because it is able to detect the up-and-down motion of your steps.
Some running apps also use data from other sensors in your phone, such as the barometer and heart rate monitor. These sensors can provide additional information about your activity, such as your elevation and heart rate.
By combining the data from all of these sensors, running apps are able to accurately track your movement and determine whether you are walking or running.
