iPhone app HemiPhysioData

HemiPhysioData is an Apple watch app to collect raw and processed data from the watch built-in sensors (accelerometer, gyroscope).
User interface is simple to select activities and other options.
The sensors data and other values are saved to a CSV file.
Send CSV files to the iPhone for further processing.
The app is specifically for those who want to collect movements data for analytics and machine learning.
The user can select the activity type, the move type, the samples per second, the wrist on which the user is wearing the watch and if the side is dominant or non-dominant.

Some details on screenshots:

UID: Predefined twenty users (U01-U20)

Activity: Movements (upper limb), Walking, Running, Misc

Move Type: It corresponds to the selected activity

Interval-Hertz: Samples per second (up to 100 samples per second)

Dominant Side: Enable it when watch is on wrist of dominant arm

Right Wrist: Enable it when watch is on right wrist

Haptic-Feedback: When enabled, the user can set the Starts In time and the logging Duration.
The user gets the alert when the logging starts (when the starts-in time finishes) and ends (when the duration finishes).
Use this option to log activity related data only.
It saves from data cleaning later.

Logged Files: Shows all saved CSV files on watch.
The user can select a file to send to the iPhone or delete from watch.

The following sensor data of the Apple Watch (WatchOS) is saved in the CSV file:

- Device Motion Processed Data: roll, pitch, yaw, rotation rate x, rotation rate y, rotation rate z, gravity x, gravity y, gravity z, user acceleration x, user acceleration y, user acceleration z, quaternion x, quaternion y, quaternion z, quaternion z.

-Accelerometer Raw Data: Acceleration x, y, and z,
