Not Another Twin Calculator

Dual Split-Screen Side by Side

Free · Designed for iPad. Not verified for macOS.

Two calculators, one screen—run side-by-side math without losing your place. Transfer results between them and keep per-side history. Free, no tracking. 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.

  • This app hasn’t received enough ratings or reviews to display an overview.

What's new in 1.0.3: - Rate the app: a quick review prompt now appears after you've completed a few calculations (never at launch, asked at most once per version). - Easier to find: refreshed the App Store subtitle and keywords so the app surfaces for dual and split-screen calculator searches. Thanks for using Not Another Twin Calculator!
