One-liner
A simple, no-frills decibel meter app that measures sound levels in real time with a clean interface and frequency analysis.
Strengths
- Accurate real-time decibel readings with minimal latency (review: 'works instantly and shows accurate values')
- Clean, minimalist UI focused on core functionality (review: 'no distractions, just the numbers')
- Supports frequency analysis (FFT) for identifying specific sound tones (keywords: 周波数, fréquence, frequenza, frequency)
- Runs reliably in background without crashing (review: 'stays active even when locked screen')
- Lightweight and fast to launch (review: 'opens in under a second')
Weaknesses
- No customizable alerts or notifications for loud sounds (review: 'would be useful to warn me if noise exceeds 85 dB')
- Limited historical data or logging features (review: 'I can’t track noise over time, which is frustrating')
- No export or sharing of measurement results (review: 'can’t save or send data to a report')
- No calibration option for device microphone (review: 'reading seems off compared to my other meter')
- Only basic visual feedback (no graph or waveform display beyond FFT bars)
Opportunities
- Add customizable sound threshold alerts with haptic or push notification triggers
- Introduce daily/weekly noise logs with charts and export to CSV or PDF
- Offer a calibration mode using known reference tones (e.g., 1 kHz at 70 dB)
- Include a simple audio recording feature tied to measurements for context
- Build a companion web dashboard to visualize long-term exposure trends
