GridCalc is an RPN spreadsheet. Enter numbers step by step, edit any value retroactively, and watch everything update instantly. Function without friction. GridCalc is a new kind of calculator for iOS. It combines Reverse Polish Notation with a visible grid so every step of your work is structured and reviewable.

Change any upstream input at any time and see immediate recalculation. GridCalc is built for people who think in steps and care about clarity: • Engineers and developers working through exact calculations • Finance and trading professionals modeling scenarios on the go • Students learning RPN and structured problem solving • Anyone who wants spreadsheet-level visibility without spreadsheet friction Designed for fast, ad-hoc modeling on mobile, GridCalc keeps your work visible, precise, and easy to continue later.
