This app could help developers to obtain the Core Motion data from the paired Apple Watch or from iPhone. Recorded data will be automatically synchronized to the iPhone. Users can view the recorded motion data directly on the iPhone in the form of line chart. Furthermore it also supports AirDrop and other forms of file sharing facility, making it easy for developers to obtain and analyze the Core Motion data. Core Motion reports motion and environment related data from the onboard hardware of watchOS device, including from the accelerometers and gyroscopes, and from the pedometer, magnetometer, altimeter and barometer.
