46 calculators in four sections. No account needed.

Forty-six calculators share one home screen.

The home screen splits into as many sections as you switch on, from one to four, and always fills the display. Each section is a glass panel holding the calculators you use most. They rank themselves by use, and you can pin the ones that must stay.

Sections switched on

    With four sections, each panel shows nine. Tap a panel’s title for the rest.

    Hover or tap a tile to see its full name.

    Say it. The right calculator opens, already filled in.

    Speech is recognised on your phone. Multiculator works out which calculator you mean, lifts the numbers out of the sentence and shows the answer.
