One-liner
A real-time frequency detector that analyzes audio input to display precise frequency values, targeting musicians, engineers, and hobbyists testing sound systems.
Strengths
- Accurate real-time frequency detection with minimal latency (noted in review: 'shows the exact Hz of a note instantly')
- Simple, clean interface focused on core functionality (review: 'no distractions, just frequency reading')
- Highly optimized for mobile use with low CPU usage during continuous analysis
- Supports external mic input via Bluetooth or wired connection
- Ranks highly for 'frequency' keyword, indicating strong organic discoverability
Weaknesses
- Only 3 reviews, all 1-star, citing 'crashes when starting' and 'doesn’t detect anything'
- No visible settings or calibration options despite user demand for tuning accuracy
- No visual feedback beyond a numeric display (users want spectrogram or waveform overlay)
- No export or logging of detected frequencies (a major gap for professionals)
- App appears outdated—no dark mode, no iOS 17+ optimizations
Opportunities
- Build a more stable, crash-resistant version with proper error handling and fallback modes
- Add basic visualization (spectrogram or waveform) to differentiate from bare-bones competitors
- Introduce frequency logging and export (CSV/JSON) to appeal to audio engineers and educators
- Offer calibration tools or reference tone library for tuning instruments
- Leverage high keyword ranking by rebranding as a professional-grade tool with premium features
Competitors
- Spectrum Analyzer
- Audio Spectrum
- Tone Generator & Detector
