A calculator. A tip calculator. A unit converter. These are not three separate apps... this is one app, and I'm calling it Mathintosh!
Mathintosh is a powerful and fun multi-function calculator for iOS, packed to the brim with helpful features, beautiful themes, and a ton of customizations.
There are no ads whatsoever, no data collection of any kind, and the app is fast, easy-to-use, and supports many powerful iOS-native accessibility features. And all functionality is available completely free, with the only an in-app purchase for theme and icon customizations.
