Scientific Graphing Calculator

HS & College Calculator is a complete, private STEM workbench for high school and college. Every feature is included for free, works offline, and is available without an account, subscription, or paywall. Built for students in math and science courses who want results quickly, with worked steps available when they help. FIVE FOCUSED WORKSPACES Calculate — basic and scientific calculation in one surface, with degree and radian modes, memory, exact fractions, and reusable history. Solve — deterministic worked steps plus local symbolic solving, simplification, derivatives, integrals, systems, and inequalities. Verified steps appear only when the app can prove each transformation. Graph — plot and save multiple functions, pan, zoom, trace, inspect value tables, and run viewport analysis. Reference — unit conversion, a searchable formula library, guided formula calculators, matrix tools, and statistics. Work — organize calculations into workspaces, pin results, save graphs and formulas, search previous work, and create local PDF study sheets. PRIVATE BY DESIGN No account. No advertising. No analytics SDK. No custom backend. Calculations stay on your device unless you explicitly choose to share a PDF or diagnostics file through the iOS share sheet. No gimmicks, gamification, or clutter. Just a dependable calculator and study workspace.
