This App can measure acceleration and rotational velocity rate by using accelerometer and gyro sensor in your smartphone. It has recording start/stop button and measured time series data will be saved as csv file to local storage.

Sampling frequency: 20Hz

[Mode]
Acceleration Rate:
- Raw Data
- Gravity Vector
- Without Gravity (it shows acceleration vector without gravity vector)

Rotation Rate:
- Raw Data
- Unbiased data (it shows rotational vector without effects of acceleration. It is useful under the situation such as riding in the car)

Note that this app can only work with smartphone (it means tablet is unavailable).
