【實用工具app】accelomate|最夯免費app

accelomate is an advanced accelerometer that can be used by experts for actual motion/position/vibration measurements, but also for education, or just for fun, by everybody who is curious about how fast their washing machine spins, or what their step frequency is while jogging, or how fast their high-rise apartment building swings in the wind (yep, we measured the resonance frequency of a skyscraper).

Modern phones and tablets have acceleration sensors for games, and to sense whether the device is held in portrait or landscape orientation. These sensors have become so good, they can be used to measure motion and vibrations with sufficient accuracy to determine the frequency spectra of those vibrations. accelomate is highly configurable in taking such measurements, and it calculates the spectra with a Fast Fourier Transformation (FFT; ideally the user should be somewhat familiar with the math and physics involved). It also displays all measurements and spectra.

Note that measurements and calculations require a certain amount of memory and CPU resources, so not everything might work on older (e.g. Android 2.x/3.x) devices. The quality of the spectra depends on the quality of the vibration sensor in your device. Our tests show that sensor quality varies over a wide range.

If you have specific questions on the inner workings, or feature requests, please don't hesitate to contact us.

The PRO version of accelomate features storing the spectra in a file for later analysis.
