Download APK FormulaBase Latest Version

FormulaBase is a fast, offline-first formula reference built for students of probability, statistics, linear algebra, calculus, optimization and machine learning.

Every card gives you more than just the formula:
• The formula itself, in clean LaTeX
• What each symbol means
• The intuition behind it — not just the math
• When to use it, and the conditions that must hold
• A step-by-step derivation, when the formula benefits from one
• A common mistake students make with it
• Practice questions to check you actually remember it

Ask a follow-up question about any formula, or request an AI-generated explanation when a topic isn't clicking.
