## What is Not Another Twin Calculator?

This is a straightforward dual calculator designed for real work. You get two clean calculators side-by-side, so you can compare numbers, transfer results between panels, and keep moving.

What it does:

Two calculators in one screen for fast side-by-side work

Move results between calculators with a tap

Separate history for each calculator

Basic calculations only — no clutter, no gimmicks

Works smoothly on iPhone and iPad

Why it exists:
Most calculators keep adding “features” that slow you down. This one stays focused: quick, readable, and practical.

If you want a calculator that feels like the classic tools—simple, reliable, and efficient—this is it.
