App privacy Measured
Vibration declares it collects no data at all — the rarest and most private label on the App Store.
Declared label
Data Not Collected
As declared by the developer on the App Store — Apple requires every app to publish this label. We track changes over time.
Vibration downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Where Vibration's downloads come from Modelled
Last 30 days: organic search, browsing the store, features and paid ads.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
51/100
faster than 51% of Business apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
What users say about Vibration
From the 34 most recent App Store reviews in the US.
Users praise the app's ability to replace expensive scientific equipment for vibration analysis and its accurate data export features. However, significant complaints focus on recent crashes, invalid receipt errors preventing use, and inconsistent performance across different iOS versions.
Mostly positive (76% of recent reviews give 4–5 stars). People like it for good value, and its features and content. Recent reviews are more negative than earlier ones.
What people like
- Price & subscription: “For the price this is amazing”
- Features & content: “There are many ways to use this cool "tool"”
- Useful: “A BSR/NVH engineer's must-have”
- Ease of use: “The interface is clean and easy to use”
About Vibration
Vibration turns your iPhone or iPad into a true FFT vibration spectrum analyzer — a portable alternative to a commercial spectrum analyzer for machinery diagnostics, acoustic testing, and hobbyist vibration analysis.
Version 5.00 is a complete visual redesign: a modern, color-coded interface built around the way vibration technicians actually work, with clean, uncluttered screens for every channel and setting, a drag-cursor readout for reading exact values on any plot, and a crisp new PDF report you can generate and share in seconds.
MEASURE FROM ANYWHERE
- Built-in 3-axis accelerometer and gyroscope — sensitivity to about 0.02g, range ±2g
- Built-in microphone input for acoustic vibration analysis
- Digiducer professional USB accelerometer support (additional Digiducer features unlockable via in-app purchase)
ANALYZE LIKE A BENCH-TOP SPECTRUM ANALYZER
- Time series and FFT frequency spectrum on every channel, with adjustable sample rate (10 Hz–100 Hz internal, up to 48 kHz with microphone/Digiducer)
- Linear-Linear, Log-Log, Log-Linear, and Linear-Log frequency display modes
- Hamming, Hanning, and Flattop windowing
- Integrate and differentiate in the frequency domain
- RMS and peak levels per channel and combined
- Frequency averaging and peak hold
- Color-coded peaks list with the top 5 peaks per channel
- Tap-and-drag cursor readout in portrait or landscape, with magnetic snap to peaks
- Selectable data length from 256 to 4096 samples, variable start delay up to 20 seconds
- DC-remove option to eliminate the gravity vector
BUILT FOR THE FIELD
- Guided accelerometer calibration with an on-screen orientation guide, live stability meter, and a locked reposition countdown
- Trigger acquisitions from one or more accelerometer channels or the microphone
- Auto-repeat and auto-save for long-duration monitoring
- Apple Watch companion app — trigger a sample and review settings right from your wrist
DOCUMENT YOUR RESULTS
- New crisp PDF report — identical on iPhone and iPad — with time series and frequency plots and acquisition details
- Open, non-proprietary format — data saves as plain CSV you can reload in the app or open in Excel, MATLAB, or Python, and email straight to your desktop
- Save data locally and transfer with the Files app
- Screen snapshots sync to your computer like any photo
In many applications, Vibration is an excellent portable alternative to a commercial spectrum analyzer. In predictive maintenance applications it can help identify bearing defects, shaft misalignment, imbalance, and structural resonant frequencies — and it's equally useful for monitoring the acceleration of part and material handling equipment.
Further development and additional features are planned. Use the email links in the app to request features or report issues.
