About

This application analyzes light to determine its dominant wavelength in nanometers, frequency in terahertz, and period length in femtoseconds. It provides real-time measurements and allows users to save their findings with notes. The app is designed for measuring colored light sources.

✓Measures dominant wavelength (nm)
✓Measures frequency (THz)
✓Measures period length (fs)
✓Real-time measurement
✓Save measurements with notes
✓Optional calibration

What's New in Light Spectrometer Wavelength

3.7.1

July 3, 2026

• Clearer readings at the edges of the measurable spectrum: out-of-range light now shows a consistent wavelength range, frequency and period length live and in your saved measurements. • Misc minor improvements Missing a feature? Let me know in a review!

Thank you!

This is a great tool … it’s spot on … I use it to see if the product actually is what they say it is with regards to light therapy. Love it!!

Response from developer

Thank you so much for the kind words! Really glad the app is proving useful for verifying light therapy products and that the app is spot on! Reviews like yours mean a lot to me as a solo developer. Happy measuring! ☀️

FAQ

What does the Light Spectrometer app do?

This app measures the light spectrum to determine the dominant wavelength in nanometers (nm), frequency in terahertz (THz), and period length in femtoseconds (fs). It is designed for analyzing colored light sources and providing real-time measurements.

What are the key features of this app?

Key features include high accuracy, real-time measurement, measurement of wavelength in nm, frequency in THz, and period length in fs. It also allows users to save measurements with notes, supports many languages, and offers optional calibration for enhanced precision.

Is this app free to use?

The app is free to download and use, but it offers in-app purchases. These purchases may be for features like calibration or other enhancements to the measurement capabilities.

What are the limitations of this app?

Smartphone cameras have inherent limitations in distinguishing very short or very long wavelengths. Accuracy may be limited below 465 nm and above 610 nm due to physical camera sensors. An automatic warning appears on the screen for these wavelengths.

Can I use this app to measure white light or the color of surfaces?

This app is not meaningful for measuring white light as it consists of a wide range of wavelengths. It is made for measuring colored light. For measuring the color of a surface or material, you would need a different application like a Colorimeter Camera Color Meter app.
