QuantFit - Publication-grade econometrics in your pocket

by
QuantFit brings applied econometrics to iPhone and iPad. Import CSV or XLSX files—or pull live data from the World Bank, IMF, Penn World Table and FRED—then run OLS, fixed and random effects, 2SLS, GMM, ARDL, NARDL, PMG, VAR, VECM and more. Inspect diagnostics, simulate policy shocks, and export publication-ready tables, charts, LaTeX, CSV and Excel. The new release turns a phone into a portable research workbench without collecting user data.

I built QuantFit because serious empirical work is still tied to a desk even when the research question is not. I wanted economists, PhD students and policy analysts to be able to pull real macroeconomic data, estimate a defensible model, inspect diagnostics and export usable results from an iPhone or iPad. This launch expands the estimator coverage, live-data workflow, post-estimation diagnostics and scenario-shock tools. I would especially value feedback from applied researchers on the models and exports they need most.
