## Review summary

Many reviews praise the app as intuitive, portable, and useful for quick, ballpark light readings and source comparison. However, a large number report it often doesn’t work reliably, with crashes, inconsistencies, and device compatibility issues. Some users note missing lumen measurements and confusing unit options, plus unclear instructions. Overall, it can be handy and affordable when it runs, but reliability and feature gaps are major concerns.

### Pros

- Intuitive and easy-to-use interface.
- Pocketable, convenient for on-the-go light measurements.
- Accurate enough for some uses and can be close to professional meters in certain conditions.
- Good value for the price.
- Versatile for comparing different light sources and for indoor/outdoor readings.

### Cons

- Frequently does not work or locks up; reliability is poor.
- Inaccurate or inconsistent results compared with high-end meters; limited sensitivity/range (won’t read above 0 in some situations).
- Missing lumen scale or unclear how to switch to lumens/foot-candle measurements.
- Poor or incoherent instructions and support (timeouts when contacting developer).
- Compatibility issues on older devices (e.g., iPhone 6/6s).
