This app employs Single Linear Correlation technics for univariate analysis and Principal Component Analysis (PCA) for multivariate exploratory analysis, including Partial Least Square Regression (PLS). The image data are acquired using the device main camera and photo album, both converted in RGB histograms. In addition, apart color channels of RGB, HSV, HSL and HSI systems are used during the univariate and multivariate processes. It is possible to send by e-mail the image data, analysis data and charts. In order to validate the obtained results, the same sets of data were tested using Microsoft Excel© and ChemoStat©. The results in both applications coincided in various combinations. This app calculates and plot: eigenvalues, eigenvectors, scores, loadings using Singular Value Decomposition in Multivariate Analysis. This app calculates and plot: slope (span), intercept (off-set) and regression (Pearson product-moment correlation coefficient) in Univariate Calibration Analysis. http://dx.doi.org/10.5935/0103-5053.20160182

Verdict
The clearest difference is in-app purchases: PhotoMetrix at none against Create Easy Chart's 1. PhotoMetrix also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). Create Easy Chart's advantage is iOS requirement (13.0 vs 15). On price and device support there is nothing between them.
