Retro Calculator⁺

THE CALCULATOR YOU'LL ACTUALLY WANT TO OPEN.

Retro Calc⁺ is 26 calculators in one gorgeous, pixel-perfect retro toolkit. It is a vintage 8-bit handheld with a modern brain: everything from an everyday calculator to a full graphing calculator, finance planners, and unit, currency, date, and time converters.

Punch in a number and watch it print to a retro adding-machine tape. Pick a theme and the whole app, including your home-screen icon, transforms with it. Every calculation saves automatically into tidy folders, so you can scroll back any time and even open a full snapshot of how you got the answer.
