The live product: statflow.claryon0.com — 8 analysis types · APA 7 auto-reports · 100% in-browser computation · freemium SaaS with subscriptions from $16/month.
The problem
Statistical software has barely changed in twenty years. SPSS costs more than most students can afford, requires a heavy local installation, and its output still has to be manually rewritten into the APA format journals demand. For researchers in the Arab world there's an extra layer: almost none of it speaks their language. As someone who has been on both sides — writing a PhD dissertation and reviewing research through Damascus Library — I kept watching capable researchers lose days to their tools.
The product
StatFlow covers the analyses that account for the vast majority of social-science research: descriptive statistics, Shapiro-Wilk normality testing, independent t-tests, one-way ANOVA with Tukey HSD post-hoc, Pearson correlation, linear regression, chi-square, and Cronbach's alpha — each with the matching effect size (Cohen's d, eta-squared, Cramer's V) computed automatically, plus "alpha if item deleted" for questionnaire work.
The workflow is three steps: drag in an Excel or CSV file, pick a test, get a report. A Smart Scanner reads the file first — detecting variable types, outliers and missing values — and suggests the statistically appropriate test, catching the errors that get theses sent back from review.
The APA 7 engine
The feature researchers actually pay for is the reporting. Every result is rendered as a complete, journal-ready APA 7 sentence — statistic, degrees of freedom, p-value, effect size and confidence interval — ready to paste into a paper, and exportable as PDF, Word or CSV. Each test also ships with reference documentation: when to use it, the formula behind it, common mistakes and acceptance criteria.
An unusual architecture decision: the data never leaves the browser
Research data is sensitive — sometimes legally so. StatFlow runs all statistical computation client-side, using the jStat statistical library for distribution functions, with output verified against SPSS to three or more decimal places. Uploaded datasets are processed entirely on the researcher's device and never reach a server. Privacy stops being a policy promise and becomes an architectural fact — and the platform scales without a compute bill.
The business model
StatFlow runs as a freemium SaaS: a permanent free tier (50 analyses a month, all 8 tests, Smart Scanner included) and a Researcher subscription with unlimited analyses, exports and cloud project saving — priced at $20 monthly with 3- and 6-month plans down to $16/month. Accounts, billing, plans and administration run on a custom PHP backend with its own admin panel. The interface fully supports Arabic — the market SPSS never bothered with.
Stack & scope
Custom PHP + MySQL backend for accounts, subscriptions and administration; a hand-written JavaScript front end performing all statistical computation in-browser via jStat; file parsing for Excel/CSV; PDF/Word/CSV export; and a bilingual interface. Product design, statistical validation, development and deployment — end to end by one developer.
