introduced the measurement of the concentration of blue lights, indicated with the G-Index value that represents the quantity of wavelengths of the colors of light ranging from 350 to 550 nm with respect to the intensity of the complete view. The G-index, indicates the shift towards red or infrared spectrum, therefore a low value of G indicates a large percentage of blue lights, a value greater than 2 indicates that the light under examination has a low concentration of wavelengths between 350- 550 nm

- This new version implements a new system for calculating the temperature of the white , the new algorithm is more accurate and precise and reliable returns values in almost all lighting conditions .
- The calibration of the white point is done automatically by the app and the user must not carry out any operation , to perform a measurement simply launch the application and view the light source to be measured .
- And the graphical interface was improved by introducing a circular indicator shows that in addition to the measured value of the Kelvin also the corresponding color shades of white intercepted .
- They have removed all the items no longer needed
- They have been made improvements to stability and compatibility with new iOS devices and minor errors have been fixed.
- It requires the iOS version 9 or above
- The iPhone4S device is no longer supported
