## What is TaguchiLab?

TaguchiLab turns the Taguchi method into a guided, step-by-step workflow so you can plan, run and analyze robust experiments in minutes.

PLAN • Define up to 15 factors with 2 or 3 levels each • TaguchiLab picks the right orthogonal array automatically (L4, L8, L9, L16, L18, L27) • Live validation warns you about duplicate levels, empty names and array limits

RUN • A clean run matrix shows every trial and its factor settings • Enter one response per run, or add replicates and multiple weighted responses • Choose your goal — Larger-is-better, Smaller-is-better or Nominal-is-best — and S/N ratios update instantly

ANALYZE • Main effects table with delta, rank and best level for each factor • Predicted optimal configuration at a glance • Main-effect plots for S/N ratio or raw response • ANOVA with degrees of freedom, sum of squares, F and p values, plus confidence intervals at 90 / 95 / 99 %

LEARN • Built-in example designs (ceramic tile, French fries, coffee brewing, 3D printing, injection molding, bread baking) with real data you can explore and modify • In-app help covering Taguchi fundamentals, orthogonal arrays and how to read ANOVA results

SHARE • Export the run matrix, level means, factor ranking and optimal setup as CSV to any app

DESIGNED FOR IPAD AND IPHONE • Full-width tables and cards on iPad; focused, card-based navigation on iPhone • Dark mode first, with a light theme that keeps the same look

TAGUCHILAB PREMIUM (optional annual subscription) • Design Library: save unlimited experiments and sync them across your devices • Keep different versions of a design and pick up where you left off • Analysis and ANOVA unlocked for every design

## Version history (last 2 releases)

### 1.1 — 2026-09-25

• Try Premium free for 7 days — ANOVA, confidence intervals, PDF reports and cloud Design Library.
• New PDF report: a clean, shareable A4 summary of your experiment with the design, run matrix, main-effects plots, recommended configuration and ANOVA table.
• Smarter ANOVA: designs where every array column is used (like the L9 examples) now pool the weakest factors into the error term, so F-ratios and p-values are meaningful. Pooled factors are labelled and every row shows its % contribution.
• The ANOVA screen explains where the error term comes from, and lets you switch pooling off.
• Fixed confidence intervals showing zero width on saturated designs, and S/N analysis with replicates reporting a zero error.
• Main-effects analysis, ANOVA, confidence intervals and PDF reports are free for everyone — Subscribe is only for cloud Design Library sync.
• Save Experiment keeps a local copy on your device without requiring Premium.
