One app, every calculator you actually need — scientific, financial, programmer, graphing, statistics, matrix, plus unit and currency conversion. Stop downloading a new app every time the math changes. You already know what your phone's built-in calculator can't do. Cal C picks up where it stops: solve for x, convert 40 units, work out an EMI, plot a graph, split a dinner bill, turn hex into binary, or check a live currency rate — without leaving the app or hunting for a website. WHAT'S INSIDE Standard — everyday arithmetic, percentages and memory functions, with a history you can search. Scientific — trigonometry, powers, roots, factorials, logs, and constants including pi and e. Equation Solver — enter an equation and get the answer, not just the arithmetic. Financial — EMI, compound and simple interest, ROI, mortgage, tax and inflation calculators. Programmer — binary, octal, decimal and hexadecimal conversion plus full bitwise operations. Unit Converter — length, area, mass, temperature, speed, energy, pressure and more. Currency Converter — live exchange rates for global currencies, in a couple of taps. Graphing — plot and compare multiple equations visually. Matrix — determinants, inverses, addition and multiplication, worked out step by step. Statistics — mean, median, mode, variance and standard deviation from your own data sets. Shapes — volume and surface area for cylinders, cones, cuboids, pyramids and more. Date Calculator — days between two dates, or add and subtract time from any date. Tip Splitter — work out the tip and divide the bill without the awkward silence. Health — BMI and other everyday body metrics. Favourites & Smart Search — pin the tools you use most, or type what you need and jump straight to it. History — every calculation saved and searchable, so you never redo work you've already done. WHO IT'S FOR Students working through coursework. Engineers and developers who need hex and bitwise on hand. Anyone comparing a loan against a lease, or converting currency before a trip. Whoever gets handed the bill at dinner. People who just want a percentage without opening a browser. WHY IT STAYS ON YOUR HOME SCREEN - Every tool one tap away — pin favourites, or search by name - Fast and accurate, with a clean layout that doesn't fight you - Works offline for everything except live currency rates - One download instead of five single-purpose calculators Your everyday calculator, reimagined. Terms & Conditions: https://obsidian-tin-ee3.notion.site/Terms-and-Conditions-32009a72d7508089a28add4379351d81?pvs=73 Currency conversion in Cal C uses exchange rate data from the Frankfurter API, which provides foreign exchange reference rates published by the European Central Bank.
