iRotorBalancer vs MultiSens
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
iRotorBalancer
This technical tool assists in balancing rotating machinery using single or two-plane methods. It connects to external hardware to measure vibration amplitude and phase, then calculates necessary correction weights and their positions. Reports can be generated and emailed.
- Single-plane balancing (Vector & Four-Runs methods)
- Two-plane balancing (Influence Coefficients)
- Real-time waveform and FFT spectrum display
- Automatic 1X peak amplitude and phase selection
- Polar plot and weight location graphics
- Report generation with plots, data, and images

iRotorBalancer is a technical tool for balancing of rotating machinery in single-plane and two-planes. The iPad application connects to an external hardware to collect the vibration Amplitude and Phase with an accelerometer and Optical Sensor, and calculates the correction balancing weights and its angular positions. NOTE: This app works with an external hardware (contact www.motionics.com for more information) FEATURES: - Single-Plane balancing using the Vector-Method (Amplitude & Phase Measurements) - Single-Plane balancing using the Four-Runs-Method (Amplitude Measurement) - Two-Planes Balancing using the Influence Coefficients Method (Amplitude & Phase Measurements) - Displays Real-Time Waveform signal - Displays Real-Time Spectrum of the Vibration Signal (FFT) - Automatic Select the 1X Peak amplitude and Phase - Polar Plot and Graphic location of the trial and correction weights - Handy calculator to estimate the Trial Weights - Angular mass distribution calculator - Permissible Residual Imbalance determination - Calculate weight removal (drilling) - Generate complete Report with Spectrum, Polar Plots, Balancing Data, Pictures from Camera or Library, Map location, Notes and Signature. - Email pdf report - Accelerometer Calibration Option - Complete help and instruction
MultiSens
This application allows users to test various machine condition monitoring sensors. It connects to sensors, displays Time Waveform and Vibration Spectrum graphs, and auto-calibrates for data acquisition.
- Test machine condition monitoring sensors
- Connect to sensors
- Plot Time Waveform graph
- Plot Vibration Spectrum (Acceleration, dB, Velocity)
- Auto-calibrate to sensors
- Data acquisition with adjustable sampling rates and sample counts
