Andy Arevalo

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.
