Refractive vs GemDetector App
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Refractive
This application calculates the refractive index of transparent materials based on wavelength. It assists optical design engineers and students by computing transmission properties, angles, and critical values. Users can also define custom materials for their calculations.
- Refractive index calculation by wavelength
- Light transmission angle calculation
- Reflection and transmission coefficients
- Critical angle and Brewster's angle calculation
- Recall of refraction formulas
- Custom material definition

Refractive is a software that calculates the refractive index of the major transparent materials in accordance to wavelength. Refractive is conceived for Optical design engineers as well as students interested in optics. All that’s needed is to select two materials to calculate their transmission proprieties. Characteristics : - Calculation of the refractive index according to wavelength; - Calculation of light’s transmission angles; - Reflection and transmission coefficients for the two materials in accordance to the angle of incidence; - Calculation of the critical angle and Brewster’s angle,; - Recall of the major refraction formulas; - Possibility to define personalized materials.
GemDetector App

This app accompanies you in the identification of gemstones. It calculates the refractive index in seconds based on the measurements you enter and helps you with suggestions to identify the gemstone. The integrated library is based on gemstones and data that are also used in gemological training. Disclaimer: The results are for guidance only and do not replace a professional gemological analysis.

Verdict
The clearest difference is iOS requirement: Refractive at 10 against GemDetector App's 15.1. On price, ads, in-app purchases and device support there is nothing between them.
