## Description

Geometry, formulas, unit conversion, and coordinate-geometry calculators that show their work the way a teacher does. Pay once. No ads, no tracking, no accounts.

Formula is a teaching-style geometry and math calculator that shows its work.
Every result walks you through the formula, the substitution, the intermediate step, and the final answer — the same way a teacher writes it on the board. Built for students, parents helping with homework, and anyone who'd rather understand the answer than just see it.
WHAT YOU CAN CALCULATE
Shapes — 17 shapes across 2D and 3D:
• 2D: Circle, Square, Rectangle, Triangle, Right Triangle, Trapezoid, Parallelogram, Regular Polygon, Ellipse
• 3D: Cube, Rectangular Prism, Sphere, Cylinder, Cone, Square Pyramid, Triangular Prism, Triangular Pyramid
Get perimeter, area, surface area, volume, diagonal, slant height — whichever applies. Many shapes are bidirectional: enter the area, get the side.
Unit Converter — 12 categories:
Length, Mass, Area, Volume, Capacity (cooking: tsp, tbsp, cups, mL, L…), Temperature, Time, Speed, Pressure, Energy, Power, Angle. Every conversion shows the factor and the multiplication.
Physics Formulas — 10 staples with N-1 / N solving:
Ohm's Law, Electric Power, Newton's Second Law, Work, Pressure, Distance/Speed/Time, Wave Speed, Density, Concentration, Pythagorean Theorem. Enter any two of three variables; the third is solved for you, with full show-work.
Coordinate Geometry — four operations on two points:
Distance, Midpoint, Line Equation from two points, and Line Equation from a slope and a point. Each draws an auto-scaled coordinate plane with the points plotted.
DESIGNED FOR LEARNING
• Show-work on every result: formula → substitution → step → answer
• Custom in-app keypad with π, ±, decimal, and a clear key in the same place on every screen
• Visual diagrams that morph to fit your input
• Tap any field to type into it — multi-field shapes auto-fill what they can derive
• Help screens on every tab — a quick "?" in the corner explains what each operation needs and what you get back
• Remembers your last tab and last unit selections between launches
• Universal: iPhone + iPad, optimized for both
NO TRACKING, NO ADS, NO SUBSCRIPTION
Pay once, use forever. No accounts, no analytics, no third-party SDKs.
