Designing a Calculator | AVENUES Digital

The fourth task of the Daily UI challenge was to design a calculator.

I stuck to the classic layout/design of a mobile calculator as it is already very intuitive for most users, and any special changes could work against usability.

However, what I considered to be a good addition was a section of "specialized" features - currency conversion, temperature measurements, regular scientific calculator, and the ability to access the most commonly used functions.

I also added a feature where the user could load their last calculation/input, even after closing the app (a lot of people accidentally close calculator apps and then end up having to re-type everything, so this would be very useful).
