We built Stratum because serious statistics on the desktop had become a choice between clunky enterprise tools and a web tab that chokes on real data. We wanted something native — fast, offline, and yours to keep. Stratum imports CSV/Excel, handles up to 5 million rows without breaking a sweat, and gives you 30+ chart types, 100+ formula functions, and the full stats toolkit: ANOVA, regression, PCA, SPC control charts, and machine learning like decision trees and clustering. It runs natively on both Mac and Windows. It's a one-time purchase — no subscription — and there's a free trial so you can throw your own data at it first. We'd genuinely love your feedback, especially on the charting and import experience. Happy to answer anything in the comments!
