Not Another Twin Calculator
Simple Dual Calculator
$0.99 · Designed for iPad. Not verified for macOS.
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.
