iPhasematch allows you to calculate the phasematching condition of nonlinear wavelength conversion such as SHG or SFM based on published Sellmeier equiations. Downconversion (OPO) can be figured out by the reverse of SFM. It is a subset of the 'Qmix' function of a famous Windows software SNLO by Dr. Arlee Smith. This App does some of what SNLO does on your iOS device. It takes the crystal, two input wavelengths, and temperature and gives the phasematching orientations, effective nonlinear optical coefficients, walk-off angles, angular tolerance and temperature tolerance. In case of SHG, it also gives spectral tolerance. In biaxial crystals, it gives only the phasematching orientations in the principal planes, i.e., either theta=90 deg. or phi=0 or 90deg. Currently supported crystals: BBO, BiBO, CBO, CLBO, LB4, LBO, KBBF, KDP, KD*P, KN, KTP, Mg:LN, Mg:sLN, RBBF, RTP, YAB. NOTE: dn/dT data for LB4 was picked up from discrete data points in the reference and linearly extrapolated. Interface should be intuitive, giving phasematching with a tap of "PM" button,refractive index with "index" button and group index with "Gp.Idx" button, for the given condition (crystal, wavelengths, and temperature). DISCLAIMER: I cannot be held responsible for the result of the calculation it gives. I make every effort to make it accurate, and bug-free, but there could be errors in code. Please just use this on your own discretion.
CloudLabs Spherical mirrors
Read full descriptionHide full description
This simulation recreates an optical table with a concave and a convex mirror, the goal is to find the focal length, the radius of the curvature and determine if the image is inverted or not. In the development of the practice, each of the mirrors can be placed on the optical table and two objects can be used to observe both the image that is formed, as well as its size, as the distance between the object and the mirror is varied.

Verdict
The clearest difference is update cadence: iPhasematch at every 7 months against CloudLabs Spherical mirrors's every 21 months. CloudLabs Spherical mirrors's advantage is iOS requirement (9.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
