Work through a quick calculation, keep the steps that matter, and change the inputs next time instead of typing everything again. START CALCULATING RIGHT AWAY Write expressions, see their results, and use named values in later calculations. Keep related steps together while you work through everyday math, study problems, or technical calculations. KEEP THE STEPS, NOT JUST THE ANSWER Save a useful calculation as a personal formula. Choose its inputs and outputs, then run it whenever you need it. Adjust a number or slider to see the results update without rewriting the expressions. SKIP THE BLANK PAGE Explore 104 ready-made formulas across 13 categories, including finance, geometry, physics, engineering, statistics, and unit conversions. Preview a formula for free, or save your own copy to customize. GO BEYOND A SINGLE NUMBER Use scientific functions, units, fractions, complex numbers, vectors, and matrices. Add plots to explore how a result changes across a range. Built-in function suggestions and a searchable reference help you find the syntax you need. YOUR MATH, ON YOUR IPHONE Calculate, browse the catalog, and run saved formulas offline. Your personal formulas stay on your iPhone: no account, cloud sync, ads, or tracking.
