What's New in Vibration

5.00

July 22, 2026

Version 5.00 is our biggest update ever — a complete visual redesign of Vibration. - All-new, modern interface — clean, uncluttered screens for every channel and setting - Color-coded channels throughout, so it's always clear which trace is which - Drag-cursor readout — touch and drag on any plot to read exact values, with magnetic snap to peaks, in portrait or landscape - Guided accelerometer calibration — on-screen orientation guide, live stability meter, and a locked reposition countdown - Brand-new PDF report — crisp, professional, and identical on iPhone and iPad, with time series and frequency plots and acquisition details - Refreshed app icon and launch experience Under the hood, everything you rely on is still here: built-in accelerometer, microphone, and Digiducer input, full FFT analysis, and the Apple Watch companion app. As always, use the email links in the app to send feedback or report an issue — thank you for using Vibration.

Simple and nonfunctional

Didn’t work for me, might work for you. Randomly cut recordings short after a few seconds then locked up and tried to text the data file, at which the cancel button greyed out. Documentation looks like freeware from 1998.

Stopped working

I had this app for several years and it suddenly stopped working -- no longer records, saves or allows contact with developer. Disappointing.

Simple and effective

I’ve used this for several years to collect vibration signals from vehicles and trickier s for research purposes. It’s easy to use and I recommend to my students.

Brilliant app

Does exactly what it claims to, measures vibration up to 50Hz.

Lots of control regarding sampling rate, time and delay.

Files can be saved and exported as CSV.

Spectrum analysis could use some more labels but nevertheless very good app.

Solid App

Bought this app over 5 years ago because the vibration sensor we were using in the lab wasn’t quite working for our need. We wanted to know the vibration noise source for a piece of equipment we were designing. With this app, we were able to determine the peak frequencies, and therefore the source of our noise. Impressed the whole team with the fact that it was an iPhone that solved the mystery. Ever since then this app has been a fun toy at home.

FAQ

What does this vibration analysis app do?

This app functions as a portable vibration spectrum analyzer. It utilizes your device's built-in accelerometers and gyroscope to acquire and display time-series vibration data. It can also process this data by removing DC bias, applying a Hamming window, and performing a Fast Fourier Transform (FFT) to generate frequency spectra.

What are the key features of this vibration app?

Key features include sampling from internal accelerometers, gyroscope, microphone, and professional external Digiducer accelerometers. It offers adjustable sample rates, data lengths, and variable start delays. The app can also remove DC bias, apply a Hamming window, plot frequency data in various formats, and export results via email or iTunes.

How much does this vibration analysis app cost?

The base application is free to download. However, certain advanced features, such as higher sample rates for the internal microphone and Digiducer accelerometers, can be enabled via in-app purchases.

What devices is this vibration analyzer compatible with?

The app is designed for iPod Touch and iPhone devices. It also features an Apple Watch companion app for triggering sampling and reviewing settings, indicating compatibility with Apple Watch models paired with compatible iPhones.

What are common use cases for this vibration analysis app?

This app is useful for predictive maintenance applications, helping to identify issues like bearing defects, shaft misalignment, and imbalance in machinery. It can also monitor the acceleration of part and material handling equipment, serving as a portable alternative to commercial spectrum analyzers.
