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.
