Review summary

Overall, users find Light Spectrometer Wavelength easy to use and capable of measuring wavelengths, including UV, with helpful developer support. However, recurring concerns include pricing/paywall frustrations, inconsistent color accuracy under real lighting, and a desire for more complete spectral data (RGB) plus a trial option before purchase. The app is useful for casual measurements but may not meet precision needs or all feature expectations.

Pros

Easy to use spectrometer app
Useful for measuring wavelength / nm
Works well for UV lamp testing and similar use
Responsive developer with updates to improve resolution
Perceived fair pricing / transparent fees (lifetime option noted)

Cons

Pricing controversy: bait-and-switch / paywalls
Color accuracy issues in real-world lighting (e.g., blue appearing orange; purple/green indistinguishable)
Limited spectral data: focuses on the dominant color and lacks RGB
No trial or demo before paying
