Motor Pitch Analyzer is a utility for measuring small motor rotation speeds and visualizing sound waveforms on iOS and Android.
The App DNA
What makes this app unique?
Hobbyists use the tool to monitor DC motor performance and identify mechanical issues like shaft runout without needing expensive tachometers.
For Hobbyists and model makers requiring a tool to measure small motor rotation speeds.
What does it look like?
Key features
Calculates rotation speed by analyzing motor sound frequencies captured via the device microphone.
Allows users to drag the graph area to specify a custom frequency range for improved accuracy.
Displays motor sound waveforms to assist in identifying shaft runout and brush conditions.
How much does it cost?
Motor Pitch Analyzer is entirely free and monetizes through ad-supported inventory.
Velocity
Maintenance developmentperformanceinternationalizationShow more...
Motor Pitch Analyzer exhibits a maintenance-level cadence, with only two releases identified in the analyzed window. The latest release, shipped 159 days ago, focused exclusively on resolving decimal separator display issues. Development appears sporadic, with significant gaps between updates across platforms. The project lacks evidence of active feature development or live operations, remaining strictly in a maintenance state.

Key takeaways for Motor Pitch Analyzer
Where is it heading?
The hobbyist diagnostic market is consolidating around tools that offer higher hardware compatibility and consistent calibration. Motor Pitch Analyzer remains exposed due to its reliance on microphone proximity and lack of a paid, ad-free experience, which limits its utility for serious users.
- Inconsistent measurement accuracy across devices leads to negative sentiment, which compounds the churn pressure already visible in the low iOS rating.
- The maintenance-only release cadence suggests no new feature expansion, limiting the app's ability to compete with more active diagnostic tools.
The SWOT
- Real-time waveform visualization enables diagnostic identification of shaft runout
- Paid ad-free tier would address top user request
