Vibration vs UniFi Verify
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Vibration
This app analyzes vibration spectrums using your device's sensors. It can process time-series data, remove DC bias, apply windows, and perform FFT for frequency analysis. Results can be emailed for documentation.
- Built-in accelerometer and gyroscope analysis
- Internal microphone and external Digiducer support
- Adjustable sample rates and data lengths
- FFT and frequency spectrum plotting
- DC bias removal and Hamming window
- Data export via email and iTunes
- Apple Watch companion app for triggering

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.

Verify gives your accounts an additional layer of security by requiring two-factor authentication (2FA) of each login attempt. With this feature enabled, users will need to provide their password and a time-sensitive verification code generated either in the app or via push notification. Verify can also supply users with a set of single-use passwords that can be stored locally on their phones should they ever need to circumvent an issue with their main 2FA method. Features: - Instant setup via QR code - Supports multiple user accounts and platforms, including Amazon, Facebook, and GitHub - Generates time-sensitive verification codes and single-use passwords either in the app or via push notification - Unlimited account support

Verdict
The clearest difference is review sentiment: Vibration at 79% against UniFi Verify's 34%. Vibration also leads on chart position (#86 vs unranked) and update cadence (every 6 weeks vs every 3 months). UniFi Verify's advantage is price (Free vs $9.99) and in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
UniFi Verify is free to download; Vibration costs $9.99 up front. Vibration sells 1 one-off in-app purchase. UniFi Verify asks for nothing beyond the download.
UniFi Verify holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: UniFi Verify has 12K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 79% of Vibration's written reviews are positive against 34% of UniFi Verify's, so the app with the better star average is not the one people write more warmly about.
Vibration ships an update every 6 weeks, UniFi Verify every 3 months. The most recent releases landed on November 10, 2026 and November 12, 2026 respectively.
