Your ready-out-the-box motion-data acquisition system.  

G-Field Recorder is an easy and powerful data acquisition and analysis system for iOS device deployments. G-Field Recorder logs, plots, and replays:

- 3-axis acceleration fields
- Rotational displacements
- Ground speed
- Altitude
- Distance
- Displacement
- Course

Use this app to assist your analysis of experiments, sports actions, drone behaviors, land vehicles, watercraft, 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 exportable in CSV format via AirDrop and other methods available on your device (e.g. Slack, email, LinkedIn ...).

Developed for NASA payloads, G-Field Recorder is resistant to data loss, continuously saving your data to permanent storage in case of a loss-of-memory event due to device damage (e.g. you crash your drone).
