jamovi (interface is slightly more intuitive; better integration with R; better data pre-processing)
JASP (better for customizable plots; statistical output can be organized / re-organized)
Note: Both of these apps can produce basic, interaction-related post-hoc tests for multi-factor ANOVAs such that each mean is compared to each of the other means. Thus for example, if the dependent variable is personal 'income' and the factors are 'region' (North vs. South) and 'industry' (manufacturing vs. service), both jamovi and JASP will generate six post-hoc t tests comparing the four groups. In this way, jamovi and SPSS improve upon SPSS, which has not been capable producing such interaction-related post-hoc tests.
