What is TRTT?
TRTT is a statistical analysis application that opens, edits and saves SPSS .sav and .zsav data files. It runs as a web app in the browser, with all computation done client-side via WebAssembly, and as a native iPhone/iPad app that shares the same analysis engine, so results are identical on every platform.
Features include Data View and Variable View editors with value labels, missing values and variable formats; frequencies, descriptives, means, crosstabs with chi-square, correlations, t-tests, one-way ANOVA, linear regression, reliability and nonparametric tests; case weighting, Select Cases and Split File; charts; and a syntax editor that runs SPSS-style commands or generates the equivalent SPSS, R or Python code from any dialog. CSV and Excel import is supported.
TRTT works fully offline: no account, no cloud, no telemetry — data files never leave the device. The web version at trtt.app is free to use; the iOS app is a one-time purchase with no subscription. TRTT is an independent product and is not affiliated with IBM.
