Yes. Every feature — frequencies, charts, t-tests, ANOVA, chi-square, sample-size calculators and PDF reports — is free, with no signup.
No. All calculations run in your browser on your own phone. Your data never leaves your device.
For standard questionnaire analysis (frequencies, group comparisons, correlations), FormStat implements the same textbook formulas as SPSS and its results are cross-checked against R, SciPy and OpenEpi. For publication-grade work, still have your supervisor or a biostatistician review the analysis.
