Max Acceleration Calculator
Calculate the maximum amount of acceleration that a shaker (from a database or user input) can output based on the mass added to the system.

Unit Converter
Convert Acceleration, Force, and Mass units to and from common units.

Sine Calculator
Based on sinusoidal motion, calculate Acceleration, Frequency, Velocity, and Displacement by inputting any two of these values.

Shock Calculator
Pick between two impact types: Plastic or Elastic, and the pulse type. Shock Calculator will find the remaining two values given two inputs: Acceleration, Impact Time, Velocity Change, and Height Change.

Strobe Light and Flashlight
Strobe your device's screen and/or flash LED from 1 - 60 Hz. Strobing helps one to see objects vibrating too fast for the eye to see. - Turn your device's screen and/or flash LED into a flashlight; this makes a conveinient flashlight during test setups.

Noise Meter
Measure minimum, current, and maximum dB from your mobile device's microphone.

Accelerometer
Measure minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes. - Zero out acceleration to calibrate for an uneven surface.
