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. No account needed, and your calculations never leave your phone.

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 to 6 simultaneous equations, and a solver for any equation.

• Statistics with lists and 12 regression types, probability distributions (normal, t, chi-square, F, binomial, Poisson and more), matrices up to 6x6, 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.

• Light and dark themes, large touch targets and screen-reader labels.

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