Refractive vs Magnetic Induction
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.

Verdict
The clearest difference is price: Refractive at Free against Magnetic Induction's $1.99. Refractive also leads on update cadence (every 10 months vs every 60 months) and iOS requirement (10 vs 12.0). On ads, in-app purchases and device support there is nothing between them.
