From Joshua Siegel:
The CloudThink Motion and Context Logger captures information from your phone sensors to a comma-separated text file for data analysis and motion studies. This application collects data from all of your phone's motion-related sensors, including the accelerometer, gyroscope, compass, and GPS. Please note, continued use of GPS running in the background can dramatically decrease battery life.Additionally, unlike other sensor-data applications available today, CloudThink's logger captures context data provided by the iPhone 5S's M7 motion coprocessor. This data is useful for studying what users do throughout the day. Finally, integration with CloudThink's own API enables the device to log when your vehicle is connected, providing accurate ground-truth to know when users are driving with a minimum of false positives (or negatives). This application allows background data logging and e-mailing of saved events, as well as FTP upload (using the filename "abc.txt"). Please note that files are not persistent, and closing the application will cause all files to be erased from memory. This will be fixed in a later revision.
