iRotorBalancer vs Bluetooth for Arduino
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

Verdict
The clearest difference is price: Bluetooth for Arduino at Free against iRotorBalancer's $799.99. Bluetooth for Arduino also leads on ratings volume (42 vs 1). iRotorBalancer's advantage is rating (5.0 vs 3.4) and iOS requirement (11.0 vs 18.5). On update cadence, ads, in-app purchases and device support 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
Bluetooth for Arduino is free to download; iRotorBalancer costs $799.99 up front. iRotorBalancer sells 2 one-off in-app purchases and Bluetooth for Arduino sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
iRotorBalancer holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Bluetooth for Arduino has 42 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 29, 2026 and October 25, 2026 respectively.
