iPhasematch vs Dinosaur Colouring Games
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
iPhasematch
Calculate nonlinear optical effects like second-harmonic generation and spontaneous parametric down-conversion. This app provides phasematching orientations, nonlinear coefficients, and tolerance values for various crystals based on Sellmeier equations.
- Phasematching condition calculation
- Sellmeier equation integration
- Effective nonlinear optical coefficients
- Walk-off and angular tolerance
- Temperature tolerance
- Supported crystal list

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.

Verdict
The clearest difference is update cadence: Dinosaur Colouring Games at every 5 weeks against iPhasematch's every 7 months. Dinosaur Colouring Games also leads on iOS requirement (8.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
