The twelve everyday analyses are free, forever — descriptives, correlation, covariance, histogram, rank and percentile, the three t-tests, the z-test, the F-test, moving average and exponential smoothing. Pro adds the modelling half: ANOVA, regression, effect sizes, the APA-style sentence, non-parametric tests, chi-square and the assumption checks.
What changed, and when. Until 20 October 2026, ANOVA and regression were free too. They are now part of Pro. Everything you have already written into your sheets is untouched, the twelve analyses above stay free with no row limit, and the preview, the new-tab output and the error messages that name the exact cell remain free for everyone — we do not sell safety.
Free — $0
Descriptive statistics · correlation · covariance · histogram · rank and percentile · t-tests (unequal,
equal, paired) · z-test · F-test · ANOVA single factor · ANOVA two-factor (with and without replication) ·
regression with confidence intervals · moving average · exponential smoothing.
No row limit, results always in a new tab, errors that name the cell.
Pro — $29 / year or $69 once, per user
Effect sizes with 95% confidence intervals (Cohen's d, Hedges' g, η²) · an APA-style sentence you can
paste into a write-up · non-parametric tests (Mann–Whitney U, Wilcoxon signed-rank, Kruskal–Wallis,
Spearman) · chi-square goodness of fit and independence with Cramér's V · assumption checks (Levene,
VIF, Durbin–Watson) · Holm-adjusted pairwise comparisons after ANOVA.
This licence is for Statwise; each of our add-ons has its own Pro licence.
The key unlocks Pro in Statwise, on up to three Google accounts. A team licence covers every add-on we publish, for a whole organisation — see team pricing. After payment the key arrives by e-mail; you paste it into the panel once. Not what the page describes? Write within 14 days and we refund in full.
The QR regression, the Welch–Satterthwaite degrees of freedom and every p-value are identical in the free and paid tiers. We do not sell being right.
After payment the licence key is e-mailed to you automatically, usually within a minute (if it is not there, look in your spam folder, then write to us and a person will send it again). You paste it once into the panel, and it is verified inside your own Google account by checking its signature. Once a day the add-on also asks our licence server whether the key is still active — that request carries the key and a random identifier for the installation, and nothing about you or your spreadsheets. If it cannot reach us, your licence keeps working exactly as it did. You can remove the key yourself at any time.
You drop back to the free tier and keep every core analysis. Being cut off from a tool you already installed is a bad way to treat people, so we do not do it.
