## Review summary

Lux Meter Light Measurement can provide basic lux readings, but its value is overwhelmed by intrusive ads, poor reliability (freezes/crashes/not opening on some devices), and questionable accuracy (inconsistent or incorrect readings). A few users find it useful for rough checks, but the ad burden and reliability/accuracy issues dominate the overall experience.

### Pros

- Measures ambient light (lux) readings.
- Some users find it helpful or 'good' for measuring lux.
- Can be used for rough judging of whether plants get enough light.

### Cons

- Excessive intrusive ads (startup ads, long unskippable ads, and ad-heavy UI) that disrupt usage.
- Reliability issues: frequent freezes/crashes and some devices (e.g., specific phones/Android versions) can't open the app.
- Significant accuracy problems: readings are often inaccurate or inconsistent (e.g., wrong lux values and screen brightness affecting results).
- Ads persist across sessions and obscure the screen, making it hard to use or interpret readings.
