Formula is a teaching-style geometry and math calculator that shows its work — and it's free for a limited time. 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 work in any direction: 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, and results list the other measurement system first — metric to imperial or imperial to metric — with the closest-sized units at the top. Physics Formulas — 10 staples: Ohm's Law, Electric Power, Newton's Second Law, Work, Pressure, Distance/Speed/Time, Wave Speed, Density, Concentration, Pythagorean Theorem. Enter any two of the three values and the third is solved for you, with full show-work. A ×10ⁿ key handles scientific notation, so values like 3 × 10⁸ m/s or 6 × 10⁻⁷ m are easy to enter and read. Coordinate Geometry — four operations: Distance, Midpoint, Line Equation from two points, and Line Equation from a slope and a point. Each plots your points on an auto-scaled coordinate plane. DESIGNED FOR LEARNING • Show-work on every result: formula → substitution → step → answer • Share your work: send the full worked solution to a classmate or paste it into your homework. Touch and hold any result to copy it. • Custom keypad with π, ±, ×10ⁿ, and a clear key in the same place on every screen • Visual diagrams that change to fit your input • Multi-field shapes fill in what they can work out • Help on every tab — tap "?" to see what each screen needs and what you get back • Remembers your last tab and units between launches • Universal: iPhone and iPad FREE FOR A LIMITED TIME — NO ADS, NO TRACKING, NO ACCOUNTS No subscriptions, no in-app purchases, no analytics, no third-party SDKs. The app collects no data. From the maker of Fraction Calculator with Work.
