Light Illusion is the de-facto standard for display calibration and colour management within the Film, Post-Production, and Broadcast industries, guaranteeing image accuracy and consistency at all levels, and uniquely supports Home Cinema at the same professional level, enabling home users to match professional colour accuracy LightSpace Connect enables ColourSpace and LightSpace display calibration programs to be used to measure and profile mobile phone screens, tablets, and connected TVs, monitors and displays, with LightSpace Connect acting as the required Test Patch Generator (TPG), enabling users and manufacturers alike to verify screen capabilities. Using Screen Mirroring any variations between a TV's HDMI inputs and direct streaming can be compared to assess any differences. LightSpace Connect is compatible with all ColourSpace, LightSpace and CalMan license versions.
Light Spectrometer Wavelength
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

Measures light spectrum to determine the dominant wavelength in nm, frequency in THz and period length in fs. DOMINANT WAVELENGTH Dominant wavelength is a concept commonly used in the field of color science and perception. It refers to the wavelength of light that appears most prominent or dominant in a given color mixture or light source. In other words, it is the wavelength that our eyes perceive as the primary color in a mixture of different wavelengths. For light with only one wavelength, such as the light from a colored LED, the dominant wavelength corresponds to the wavelength of that light. KEY FEATURES • High accuracy • Real-time measurement • Measures light wavelength in nanometers (nm) • Measures light frequency in terahertz (Thz) • Measures light period length in femtoseconds (fs) • Easy to use • Save measurements with notes • Supports 40 languages, including english • Optional calibration for enhanced precision MEASURING 1. Find a white surface, such as a plain piece of white paper 2. Point your camera at the surface illuminated by your target light source 3. The app gives you accurate measurements in real-time LIMITATIONS Smartphone cameras have limitations when it comes to distinguishing between different very short, or very long wavelengths. More specifically, on many devices the accuracy below 465 nm and above 610 nm is very limited. This is due to the physical camera sensors in the devices. An automatic warning appears on the screen for these short and long wavelengths. WHITE LIGHT Note that is not meaningful to measure the dominant wavelength of white light as white light consists of a wide range of wavelengths, with no wavelength dominating. This app is made for measuring colored light. If you are interested in determining the color temperature of white light, please instead use our popular White Balance Kelvin Meter app. COLOR OF SURFACES If you want to measure the color of a surface or material, rather than of light, please instead use our popular Colorimeter Camera Color Meter app. Privacy Policy, https://spectrometer.contechity.com/pp.html End User License Agreement, https://spectrometer.contechity.com/eula.html CONTACT I value your feedback.

Verdict
The clearest difference is rating: LightSpace Connect at 5.0 against Light Spectrometer Wavelength's 4.2. LightSpace Connect also leads on monetization model (free vs free with in-app purchases) and update cadence (every 3 weeks vs every 2 months). Light Spectrometer Wavelength's advantage is ratings volume (94 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. LightSpace Connect sells 3 one-off in-app purchases and Light Spectrometer Wavelength sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
LightSpace Connect holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Light Spectrometer Wavelength has 94 ratings behind it against 1, so its average is the more settled of the two.
LightSpace Connect ships an update every 3 weeks, Light Spectrometer Wavelength every 2 months. The most recent releases landed on October 7, 2026 and October 13, 2026 respectively.
