This accelerometer app measures and displays a graph of G-Force vs. Time(s) that can be exported in an e-mail as a .txt attachment with comma separated values (csv). G-Force and acceleration measured in the x, y, and z dimensions are displayed separately on the graph, and the total vector sum is displayed digitally.

android.permission.WAKE_LOCK: Used to keep the device awake only when recording accelerometer data to csv. (Example: After pushing the record button, the app will continue to collect data even when placed in a pocket during a roller coaster ride, and will turn off only after data recording has been stopped.)
android.permission.WRITE_EXTERNAL_STORAGE: A csv file is created and modified on the phone's internal memory.
