Mindarin introduced me to their wonderful new iOS app that I have had the pleasure of using for the last couple of weeks, that not only offers a wonderful user experience, but also features a beautifully minimal display. The app is Luna — a calculator that makes calculations instantly as you type, while keeping your expression clean and readable. It allows you to save your results as well as complete calculations, operate them, edit them, and create lists. The designers explain:

We designed Luna to be truly useful. Most iOS calculators differentiate by adding cute gestures or pretty colours, our goal was to create the ultimate useful calculator, one you could use to do a quick operation or keep track of your business expenses. But keep it simple, clean and minimal.

Admittedly, there are a couple of minor bugs with Luna, but as with every newly developed app, the more it is used, the better it can become. It is the aesthetics of Luna that leaves me impressed though along with the feature to alternate between black and white themes with a simple shake of the device.
