POLY / multiscreen calculator

Linked math across screens

$2.99 · Designed for iPad. Not verified for macOS.

A faster way to calculate across multiple screens. Create linked workspaces, reuse values instantly, and keep complex calculations organized without losing clarity. POLY is a multiscreen calculator built for people who need more than a single line of math. Instead of working inside one display, you can create multiple calculation screens, name them, and move between them freely. Each screen can hold its own expression and result, and you can use one screen’s value inside another to build larger calculations step by step. POLY is designed to make complex workflows feel simple: - Create as many calculation screens as you need - Rename screens for better organization - Tap an operator, then tap another screen to use its value - Keep previous expressions visible above results - Switch between a standard keypad and an advanced function keypad - Use scientific tools like powers, roots, logs, constants, and more - Copy results with a long press - Work in a clean portrait layout designed for fast use POLY is ideal for chained calculations, comparisons, budgeting, engineering notes, study sessions, and any workflow where a normal calculator becomes limiting. If you think in steps, not just in single operations, POLY gives your calculations the space they need.
