#004 Calculator

October 29, 2016

Browsing through Dribbble and Twitter, there are already hundreds of redesigns for the standard calculator.

I decided to design a specialty calculator based on the PHQ-9 Questionnaire, a screening tool for Depression used in the NHS.


Prompt: “Design a calculator. Standard, scientific, or specialty calculator for something such as a mortgage? Is it for a phone, a tablet, a web app? ”

The icon design was kindly released by Vincent Le Moign, published on Sketch App Resources, for free and commercial use.

The design itself is quite simple and minimalist. I love how an icon could change the whole feel of the app, making it seem much more approachable and inviting.

This isn’t a complicated app to build, and I may turn this mockup into a working iOS app in the future.
