Smart Calculator vs SmartCalc Pro

"What numbers did I input?” "Was the number I input correct?” Everyone must have caught on such anxiety while using a calculator. SmartCalc is a calculator that wipes out such anxiety. Because, after a calculation, inputs are displayed as you input, and also one input number can be changed for the next calculation. [Instructions] • To recall calculation history, tap "＜ Prev" key until you find the history you want. After you tapped "＜ Prev" key, if you want to recall a newer history, tap "Next ＞" key until you find it. • To clear the calculator completely including calculation history, close SmartCalc. • To clear the calculator except for the set memory and the independent memory on MR-line, tap "C" key and then tap "AC" key appeared, that is, double tap "C" key. • To clear the independent memory on MR-line, tap "MR" key and then tap "MC" key appeared, or swipe on MR-line. • To completely clear the number you have just input on 1st-line or 2nd-line, tap "C" key. • To erase a right end number at 1st-line or 2nd-line framed in the input mode, swipe on the line. • To change one of input numbers after a calculation, please tap the input line display to input a new number. • Tapping Result-line display is a convenient substitute for tapping "=" key. [Features] • SmartCalc is a calculator with a large 4-line display, which consists of 1st-line, 2nd-line, Result-line and MR-line. As all numbers related to a calculation are displayed on the lines all together, a user can check the calculation at a glance. • SmartCalc doesn't require any special operations. Anyone can use SmartCalc easily. • SmartCalc equips the set memory in addition to the general independent memory. The set memory automatically memorizes calculation history of all sets of calculated input numbers, an arithmetic operator and a result number. • Can be used in environments where either a period or a comma is used as the decimal separator. The developer assumes no responsibility for any loss or claims by third parties which may arise from the use of this app.

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. Made by WebbingStone — webbingstone.com
