Cal

Here’s your calculator app! It’s built as a free, open-source React component. Features include:

– **Basic operations** — add, subtract, multiply, divide
– **Utility keys** — AC (clear), +/− (toggle sign), % (percentage)
– **Recent history** — shows your last 5 calculations above the calculator
– **Smart display** — font shrinks automatically for long numbers
– **iOS-inspired design** — dark theme with the classic layout

All built with pure React, no paid libraries or APIs needed.
