MultiCalc
More than one calculator, at the same time. Keep the grocery total, the rent split and the invoice going at once, without losing one to start the next.
Two kinds of calculator
In this app. Adds another calculator to your list. Each keeps its own display, its own history and its own colour. Switch from the button at the top or by swiping the display sideways. Works on every phone.
Phone calculator. Opens another copy of the calculator your phone already came with, outside MultiCalc, as its own card in Recents. Whether a phone allows this is up to its manufacturer, so MultiCalc asks your device directly and turns the button off, with the reason, where the answer is no.
The rest of it
- Round keys with space between them, that fire as your finger lands and again as it slides on
- A history tape per calculator, and any past result goes back on the display in a tap
- Export to text, CSV or JSON, and import a JSON export back
- Decimal arithmetic, so 0.1 plus 0.2 is 0.3
- Light, dark and system themes
No account, no server, no ads
MultiCalc has no internet permission at all, so nothing you type can leave your phone. There is no analytics and no tracking. The privacy policy is one page and says the same thing at greater length.
