SmartCalc Pro: Calculator

SmartCalc Pro opens straight to a clean, fast calculator — and one tap on the menu turns the whole screen into any of 24 practical calculators. Everything works offline, no account needed, and your numbers never leave your device.

A REAL GRAPHING CALCULATOR Switch to Scientific and get a full graphing calculator: • Calculate: fractions, powers and roots, logs, trig and hyperbolic functions, derivatives, integrals and sums, nCr/nPr, degrees-minutes-seconds, complex numbers, variables, Ans and 20 physical constants — shown as they look on paper. • Graph: up to six functions (y=, polar, parametric, inequalities). Pinch to zoom, tap to trace, and find roots, maximum and minimum, intersections, y-intercepts, areas under curves and tangent lines. • Table of values and an equation solver (polynomials up to degree 6 with complex roots, 2–6 simultaneous equations, and a solver for any equation). • Statistics with lists and 12 regression types, probability distributions (normal, t, χ², F, binomial, Poisson and more), matrices up to 6×6, and Base-N (hex, binary, octal with logic operations).

24 EVERYDAY AND PROFESSIONAL CALCULATORS • Everyday: standard and scientific calculator, currency converter (160+ currencies, works offline with saved rates), unit converter, age and date calculator. • Electricity: electrical power (DC, single-phase, three-phase), electricity consumption for multiple appliances, battery runtime. • Solar: system size, number of panels and roof space, inverter sizing, battery bank sizing, payback period. • Home: air-conditioner capacity, paint, tiles and concrete — with compact forms that fit several measurements on one row. • Business: profit, margin and markup, break-even, VAT and commission, digital-marketing metrics. • Car: fuel cost, travel time, EV charging.

MADE TO BE CLEAR • Results update as you type, with a "Details & steps" view that shows the formula and every step. • Save calculations to history, favourite the tools you use most, share or copy results. • Full Arabic and English with right-to-left support, light and dark themes, and iPad layouts that show the menu, inputs and results side by side.

Estimates for electrical, solar and construction work are for planning only — always follow local codes and consult a qualified professional.
