UI Challenge #004 - Calculator

Challenge # 004: “Design a calculator”

Since developing a calculator for a smartphone or desktop does not offer many challenges, I chose the Apple Watch as a device since the space limitation seemed to be a great challenge.

Honestly, I think the standard Apple Watch calculator works just fine, and although touch can be difficult with limited space, you can ask Siri to solve small calculations. Anyway, as part of the challenge, I tried to develop my own version.

I assumed that the Apple Watch calculator had the function of solving simple operations, since for more complex operations it would be better to use a more suitable device.

The idea was to use gestures to choose between mathematical operations to reduce the number of buttons, leaving more space for the essentials and making it easier to touch the numbers.
