Formula Helper

Formula Helper helps you work through textbook-style problems without clutter: choose a formula, enter what you know, pick which variable to solve for, and get a clean result with substitution and short solution steps.

What you get

Organized catalog — Mathematics, Physics, Geometry, and Finance, plus search to find formulas fast.
Flexible solving — Many formulas support more than one “unknown”; switch the target variable when you need a different quantity.
Sensible validation — Clear messages when inputs are missing or invalid (e.g. division by zero).
Readable output — Adjustable decimal precision so results match how you want them shown.
Favorites & history — Star formulas you use often and revisit recent calculations with a tap.
Themes & display — Light, dark, or system default; toggles for formula card, steps, and unit hints.
Simple diagrams — For selected formulas, a minimal visual helps you see lengths, radius, motion, and similar ideas.
Who it’s for
Students, teachers, and anyone who wants quick, structured calculations using standard formulas—without unnecessary permissions.
