What Simple Calculator covers

Simple Calculator is an Android calculator that handles four basic operations and a separate engineering calculator. The developer describes it for simple sums and technical calculations alike.

Beyond the calculator screens it includes a calculation history and a set of 23 converters, so arithmetic and small unit or money problems can be handled in one place.

Basic math and the engineering calculator

The engineering calculator opens from its own icon, separate from the standard four-operation screen. The listing describes it as covering engineering calculations, though it does not list the individual functions.

Each calculation is kept in a history page. Tapping a past entry brings its formula back so it can be used again, and a long press on an entry deletes it.

Converting units, money and personal figures

The unit converter has 23 categories. Physical measures include length, area, volume, mass, data, speed, time, temperature, frequency, angle, pressure, force, power and fuel.

Money and personal figures are covered by currency, discount, GST, split bill and loan, along with BMI, age, date and numeral system conversion.

Night mode, colors and display settings

Night mode is switched on from its icon, and settings let you set a time range for it to run automatically. A color can be chosen from settings as well.

Other settings change the language, add a beep or vibration when a button is pressed, pick the numerals shown (the listing says all numerals are supported) and select a number format.
