## What is Cathy's Calculator for iPad?

This is 100% free with no ads, no tracking, no permissions, and no logins.

Made for people who remember the 80's, this features large buttons and is easy to use.

Arithmetic is precise and where approximation is used (e.g. sqrt), the equals sign is replaced with a squigle-equals.

There is a command history with scrollback, meant to feel like the old ribbon printers. You can copy a number to the clipboard by tapping on it.

This calculator was made for my mother, Catherine.
