SpeedCrunch

Calculate with high precision, reusable variables and an editable history

Meet SpeedCrunch

SpeedCrunch is an open-source scientific calculator for Windows, macOS, and Linux. It combines high-precision arithmetic with complex numbers, built-in functions, constants, units, and vector or matrix support. Users can define their own variables, functions, and units for recurring calculations. Calculation history can be rewritten, and settings can be adjusted for individual results. Multiple sessions can be arranged in tabs, panes, or windows, separating different lines of work. Customizable layouts and keypad presets let students, teachers, or technical users arrange the workspace around the calculations they need to enter and revisit.
