A little over 8 years ago, I started an iOS app to scratch an itch - I needed a powerful calculator when I was at university studying physics. What I found is that there are plenty of powerful calculator apps out there, and plenty of calculator apps that have a fantastic user interface, but about zero that have both at the same time. I come from a background of both maths and design, so I wanted to be the one to create it.
The app has had one complete rewrite so far - but that's where macOS support came in.
The design principles I started with have remained throughout - an interactive editor that lets you see and adjust what you’ve entered, and a modern approach to a calculator keyboard. I built this so it would be good enough for a physics degree. It supports graphing, unit conversion, numerical solvers, as well as imaginary numbers, matrices, series summations, numerical differentiation and integration. The keyboard makes a clean break from traditional calculators. Buttons are grouped into submenus, exactly like the alphabetical keyboard on iOS. Just like when you press and hold on a to get things like à, â, and ä, press and hold on degrees to get arcminutes and arcseconds; or press and hold on sin to get arcsin. This means the keyboard can be kept visually simple, but still retain all the over 100 buttons available. If you prefer to use your physical keyboard, that works too. For simple things - like 1 - it'll input that directly. Everything all other buttons are done via suggestions - type 'sin', then hit enter.
It's a paid app with a simple model - you pay to download it and there's no subscriptions. One purchase will unlock the app on macOS, as well as iOS and iPadOS, and iCloud will sync your settings over. The only IAPs are tips for anyone feeling extra generous - they don't unlock any features
I'd love to hear your feedback!
