Multi Angle Meter For Watch vs Care Sensors

INSTRUCTIONS When the watch is tilted, the tilt angle is displayed in the three axes of yaw, pitch, and roll. Long-tap the number of an angle degree on the screen: The angle is set "On the ground" is displayed in the upper left corner of the screen.　 Double-tap the number of an angle degree on the screen: The angle is reset and "On the table" is displayed in the upper left corner of the screen. Each time you double-tap, the angle is reset. Long press the number of an angle degree on the screen to initialize the angle. The angle based on the ground is displayed. "On the ground" is displayed in the upper left corner of the screen. Setting: You can set the angle notification function. *Screen Description On the ground: Default value. Displays the angle to the ground. On the table: Displayed when the angle is reset. Yaw: Rotation angle of the horizontal plane with the vertical axis. If the Angle Notification function is set to On, the angle will be displayed in red from ±5 degrees of the set angle. If Vibration is set to On, The angle is displayed in red letters with vibration. Roll: Angle of rotation on the front-back axis. If the Angle Notification function is set to On, the angle will be notified in orange from ±5 degrees of the set angle. (If Vibration is turned on, The angle is displayed in orange letters with vibration. Pitch: Angle of rotation on the left/right axis. If the Angle Notification function is set to On, the angle will be notified in green from ±5 degrees of the set angle. (If Vibration is turned on, The angle is displayed in green letters with vibration. Setting: Displays the angle set by the angle notification function on the Setting screen. Save: All angles (yaw, pitch and roll) of the notification can be changed to the current angle. Note: The angle displayed is the angle detected by the gyro sensor of this watch. To measure the angle accurately, use a calibrated angle meter or inclinometer instead of this application.

CareSensor turns your Apple Watch into a structured motion sensor recorder for research, machine learning, rehabilitation, and any study that needs labelled inertial sensor data from a wearable. DESIGNED FOR STRUCTURED DATA COLLECTION Every recording is tagged before it starts — participant, data category, sub-category, body side, and sampling rate. That metadata is embedded directly in the output filename so your dataset stays organized without any manual labelling after the fact. Fully customizable categories mean CareSensor fits any label schema. SENSOR RECORDING Record Device Motion (attitude, quaternion, rotation rate, user acceleration, gravity) and Raw Accelerometer simultaneously at 5–100 Hz. Choose from four CoreMotion reference frames. A 5-second countdown lets the subject get into position before sampling begins. LIVE SENSOR STREAMING Stream and visualise up to 2 sensor types in real time on both the Watch (5–30 Hz) and the iPhone. Verify signal quality before committing to a recording. FLEXIBLE FILE MANAGEMENT Files are saved on the Watch. Send them to your iPhone individually (swipe to send) or all at once with progress tracking. Preview any CSV or JSON file instantly with native QuickLook, then export a ZIP archive — organised by participant if needed — ready for MATLAB, Python, R, or any analysis toolchain. PARTICIPANT MANAGEMENT Manage participants, categories, and sub-categories on the iPhone and sync to the Watch with one tap. Default data includes 16 categories covering common rehabilitation exercises — or replace them with any classification structure you need. PRIVACY-FIRST All sensor data and participant information stays entirely on your devices. No data is sent to any server. No account required. No ads. REQUIREMENTS • Apple Watch Series 4 or later, watchOS 10.0+ • iPhone with iOS 17.0+ • Watch must be paired to the iPhone • Motion & Fitness permission on Watch
