Device Motion Detective vs G

Detect the device motion detail information and save the information into the core data system. The user could view the past motion record from the data base system. The user could view the real time device motion list or the motion graph. The app can receive four types of motion: raw accelerometer data, raw gyroscope data, raw magnetometer data, and processed device-motion data (which includes accelerometer, rotation-rate, and attitude measurements). The current version could record the device motion data for 20 minutes when tap the record button once. After 20 minutes, the user could tap the record button again. During recording, the app will insert the motion data to the database every second. Only after recording the motion data, the feature of view record motion data will display the record information. In current edition, when the device shutdown, the database information will be cleared automatically. In short, the app may be useful to some engineering users or other users who need the detail device motion data. Best wishes.

G-Field Recorder is an easy-to-use and powerful data acquisition and analysis system for iOS device deployments. G-Field Recorder logs, plots, and replays: - 3-axis acceleration fields - 3-axis rotational displacements - Ground speed - Altitude - Distance - Displacement - Course Use this app to assist your analysis of experiments, sports performance, drone behaviors, land vehicle and watercraft actions, security applications, structural behaviors, and more. All of your data is logged on your device, where you may retain it indefinitely, share, or delete the files of your choosing. All data files are easy to export in CSV format via AirDrop and other methods (e.g. Slack, email, LinkedIn ...) available on your device. Developed for NASA payloads, G-Field Recorder is resistant to data loss from impacts, continuously saving your data to permanent storage in case of a severe upset event that damages your device (e.g. you crash your drone). Features: - Logs and plots of motion data: -- 3 Axis Acceleration Field -- 3 Axis Rotations (Pitch, Roll, and Yaw) - Virtually unlimited recording time.  The collected data is automatically stored in as many sequentially indexed files as required, up to about 5 MB per file (for easy search and review). Data storage capability is up to the max storage availability on the device. - Programmable data acquisition control:  - Relative start time  - Absolute start time - Relative stop time - Acceleration reference frame is configurable: -Choose to ignore or sense gravity - Select reference frames: Proper, Fictitious, or Coordinate acceleration - Remote control and monitoring via Apple Watch: - Apple Watch can start and stop data collection, overriding any device-programmed start and stop times  - Apple Watch can set the acceleration reference frame - Set sampling frequency from vanishingly small (e.g. 0.001 Hz) up to 100 Hz - Computed averages and extrema of are automatically logged for all recorded motion data - Rewind and instant playback of recorded data - Text notes and an image can be added to each stored data file - Selectable animated icon graphics GPS Package In-App Purchase (recommended ) -- Ground Speed, Course, Altitude -- Distance & Displacement -- Illustrated path overlayed on Apple Map
