## Review summary

The Sound Meter app is praised for being a simple, useful tool that does real-world noise measurements and has a visually appealing interface. However, repeated concerns include missing weighting options (A/C), a capped 93 dB range, removed calibration controls, and occasional crashes, leading to inaccuracies for high-level measurements. Overall good for basic use but limited for precise, professional tasks.

### Pros

- Does what it promises and is a straightforward, easy-to-use noise meter.
- Useful for real-world measurements and practical observations (e.g., checking noise on public transit).
- Visually appealing UI and functional design.
- Free to use with no ads.

### Cons

- Lacks A/C weighting; no option to select weighting.
- Measurement range is limited (~93 dB), causing inaccuracy at higher levels.
- Calibration options per brand removed / calibration features unreliable.
- Stability issues; crashes on some devices.
