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.
Four primary modes:
• simple calculator: fast, easy, and all the basics are covered
• scientific calculator: functionality of all kinds, covering every calculating need under the sun
• tip calculator: intuitive design gets you a tip based on your preferred percentage, now more customizable, with innovative rounding and splitting features
• unit converter: convert dozens of units across 10 modes, including a live-updating currency conversion and a unique timezone conversion
And two additional new modes:
• Fraction mode with separate numerator and denominator number pads for quick and easy fraction calculations
• Pythagorean theorem mode for easy calculations of any missing side
Features include:
• In-app purchase for 20 additional incredible premium themes ranging from monochrome to vibrant to retro-inspired technology, and more
• In-app purchase also include the ability to pick a custom app icon from a colorful selection of 11 choices
• Customizable fonts, button shapes, glass v. flat v. 3D icons, and so much more
• Paper tape shows the history of all your calculations in one convenient place
• Share values across the app, from one calculator or mode to another, using a handy banner at the top of the screen
• Apple Watch app that syncs your selected theme over from the iOS app
• Widget and Control Center and Quick Actions support
Many exciting features continue to be added that you won't want to miss!
The functionality built into one single calculator app is incredible! I love the ability to view the history of all operations, and quickly transfer numbers between different calculators. The personalization options within the app are also amazing.
