CB Calc - Custom Calculator
Build your own calculator
$1.99 · Designed for iPad. Not verified for macOS.
A calculator that adapts to you: build custom buttons for the math you actually do, from unit conversions to multi-step formulas, in seconds.
CB Calc (Custom Button Calculator) is a clean, fast four-function calculator — with one big difference: you can add your own buttons.
Tired of repeating the same calculation? Build a button for it once, and it's there whenever you need it. Whether it's a quick conversion, a recurring formula, or a constant you use all the time, CB Calc lets you turn it into a single tap.
WHAT YOU CAN BUILD
- Constants — save a value or formula (like π×2) as a one-tap button
- Transformations — apply a function to whatever's on the display, like sqrt(A) or A². Example: A×0.15 — calculate a 15% tip
- Two-number formulas — create your own operators that work just like +, −, ×, ÷, but do exactly what you need. Example: (A+B)÷2 — an average of two numbers
- Currency conversion — pick any two currencies and get a dedicated conversion button, with rates kept up to date
- Math functions — sin, cos, tan, log, ln, sqrt, and exponents, all available when building your buttons
MADE TO FIT YOUR WORKFLOW
- Reorder your custom buttons however makes sense to you
- Simple, guided button editor — no coding knowledge required
NO CLUTTER
No ads, no account required. Just a calculator that grows with you.
