Regression Analysis

REGRESSION ANALYSIS is a powerful, intuitive, and professional-grade tool designed for engineers, scientists, students, and data analysts who need fast, accurate, and visually clear regression modeling directly on iPhone, iPad, or Mac. Whether you're studying experimental data, validating correlations, or preparing reports, this app gives you the precision and flexibility you need in a clean, modern interface.

Build multiple independent projects, each with its own data, regression type, formatting, theme, and visualization settings. Enter your data manually or paste it from external sources, then instantly generate best-fit curves using a variety of regression models, including:

• Linear Regression

• Polynomial Regression (custom degree)

• Power Regression

• Exponential Regression

• Logarithmic Regression

• Inverse Regression

• Logistic Regression

Every model includes equation details, summary statistics, and evaluation metrics to help you measure accuracy and interpret your results confidently.

Visualize your data with a fully customizable chart: change series colors, adjust appearance themes, and switch regression types on the fly to compare fits instantly. Predict values for any given point and see how the model behaves beyond your sample range.

Your projects sync securely through iCloud, keeping your work consistent across all your Apple devices—no login, no server accounts, no data collection.

When you're ready to share or document your results, export your samples, regression summaries, equations, and charts directly to Excel (.xlsx) with beautifully formatted, ready-to-use worksheets.

Explore the built-in literature section to deepen your understanding of regression concepts, model behavior, and statistical interpretation—all explained clearly for both beginners and advanced users.

REGRESSION ANALYSIS is designed to be fast, accurate, private, and beautifully simple—your complete regression toolbox, available anywhere.
