G-Field Recorder is a "ready out the box" motion-data acquisition system

Proven in space launch and recovery, use this intuitive, reliable, and programmable app to perform your acquisition of motion data -- no coding or electronics required!  Just download to an iPod Touch, iPhone, or iPad. It runs in foreground or background.


Log acceleration, rotation, speed, distance, displacement, heading, and altitude. Utilize GPS to map your course and for turning (yaw) course reference. 

You can easily review and analyze data in table and graphical forms directly on the app or export data as a CSV file to another platform via AirDrop, email, Slack, or many other file share opportunities already on you device.
