## Review summary

Reviews are mixed but generally positive: users praise the app’s controls, waveform capture, and calculation accuracy, as well as overall quality and hardware support. Repeated concerns focus on input connectivity failures, reliability on certain devices or after updates, and inaccuracies in waveform representation (square waves and sine/triangle shapes). Some users also request clearer setup instructions. Overall sentiment leans positive, but reliability and accuracy issues limit universal adoption.

### Pros

- Good controls and intuitive UI
- Captures waveforms and frequencies effectively
- Frequency and time calculations appear accurate
- High-quality design and performance, including with the hardware module
- Overall positive reception across reviews (Excellent/Very good/Nice/So good)

### Cons

- Input/mic connection issues with TRRS/mic input
- App instability and compatibility problems on some devices and after updates
- Waveform accuracy issues, including incorrect square-wave display and inconsistent waveform shapes
- Onboarding/usage guidance could be clearer
