GraphCalc is a complete math toolkit for students, teachers, and anyone who needs to calculate, graph, or solve — all in one app, all on your device. CALCULATOR (Free) A full scientific calculator with trigonometric, logarithmic, exponential, and root functions, plus a live preview of your result as you type. GRAPHER (Free) Plot any function and explore it with pinch-to-zoom and pan. Add a slider for any parameter (like the “a” in a·sin(x)) and watch the curve move as you drag it. See exactly where two curves cross, find roots and extrema automatically, and share a clean image of your graph. UNIT CONVERTER (Free) Convert length, mass, temperature, area, volume, speed, time, pressure, energy, power, and digital storage — all offline. EQUATIONS Solve systems of linear equations (2 to 5 variables) and quadratic equations, step by step. MATRICES Compute determinants, inverses, and transposes, or add, subtract, and multiply matrices up to 4×4. CALCULUS See the full worked solution, not just the answer: • Derivatives — every rule applied, one step at a time (product, quotient, chain, power) • Limits — direct substitution, with L'Hôpital's rule applied automatically when needed • Integrals — numeric area under any curve Equations, Matrices, and Calculus (with full step-by-step work) unlock together with a single one-time purchase of $4.99 — no subscription, no recurring charges, yours forever. GraphCalc works completely offline: nothing is ever collected, uploaded, or shared. Available in English and Spanish, matching your device's language automatically.
