A new calculator software cannot really bring attention (https://chachatelier.fr/chalk/) However, I wrote a full article explaining why I had to build something "new" that does not behave like usual desktop calculator softwares : TL;DR All "small" calculator softwares I know share the same design flaws. And the GUI is not the only stumbling block in their poor efficiency. Handling correctly numerical approximations - expected or not - is crucial to trust the results.

If you compute 1 / [-1, 2] in regular interval arithmetic, you get either [-∞, +∞], or you have to say that the operation is undefined. Both solutions are virtually useless.

A spent a few days designing and programming a calculator app that I thought would be intuitive and simple. It utilizes a single gesture control as well as shake detection. It's free for iPhone: http://itunes.apple.com/us/app/numbrs/id517346105?mt=8 If you download it, let me know what you think.
