This app was an academic tool for internal use, but Google doesn't allow to publish private link-only betas so that's why it is publicly available. It was designed for measure small experiments using device sensors/actuators.

You can try it if you want, it should be self explanatory.

Features:
- Ability to read and record the accelerometer sensor.
- Ability to read and record the microphone sensor.
- Ability to play sound of a specific frecuency.
- Ability to turn on/off the vibrator.
- List of raw information of all the device sensors.
- Automatic predefined experiments
