The app listing, the version table and the download step are laid out by this site’s stylesheet. With stylesheets switched off, or blocked before they arrive, none of that layout exists, so the page is not shown.

All-In-One Calculator: scientific, currency and unit tools

By Hafiz Rahman

Editor, tools and utilities

Scientific mode with trig, logs, exponents and complex numbers
Graphing mode that plots functions you type in
Currency converter with 160+ currencies at live exchange rates
Unit converter for length, weight, volume, temperature and more
Equation solver for linear and quadratic equations, with step-by-step working

What the calculator covers and who it suits

All-In-One Calculator puts a scientific calculator, a graphing mode, a currency converter, a unit converter and a set of finance, maths and health calculators in one free app. The listing presents it as a general tool for everyday use, so it fits anyone who regularly needs more than basic arithmetic, from school maths to checking a loan or converting a recipe.

The scientific side handles trigonometry, logarithms and exponents, and the listing says it returns fractions and complex numbers as well, so √-1 gives i and 0.3333 can display as 1/3.

Scientific, graphing and memory functions

Calculations use the usual memory keys: MC, M+, M- and MR. A history log keeps past calculations, and you can attach notes to individual entries so you can find them again.

The graphing mode plots functions, which lets you see how an equation behaves rather than only read its result. Results from the scientific mode feed the same history, so working through a multi-step problem leaves a record.

Currency and unit conversion

The currency converter covers more than 160 currencies using live exchange rates, and it can convert several currencies at once against one amount. The listing says the converter works fully offline, so you can run conversions without a connection.

The unit converter groups units into length, weight, volume, temperature, area, speed, pressure, power, energy and digital storage, plus cooking measures, shoe sizes, regional, historic and scientific units. It also handles combined units such as feet with inches or litres with millilitres in a single entry.

Maths, money and body calculators

The maths tools include percentages with discounts, averages and proportions, a solver for linear and quadratic equations, and area and volume calculators for flat shapes and solid bodies. The equation solver shows step-by-step solutions.

For money, the app has tip and sales tax calculators, a loan and interest calculator and a unit price comparison for shopping. Date tools give your age, the gap between two dates and the time between two dates, and health tools cover BMI, body fat and calories.
