A simple browser
In my neverending exploration of minimalism in technology, I stumbled uppon this super simple Mac app called Monochrome. It's a neat web browser and its most unique feature is the fact that it only allows you to use it in what you can call a mobile view.
The viewport goes from 320x480px (the original iPhone screen size) to 414x896px (the current iPhone XS Max screen size) and that forces you to browse the web in a very different way. Big fan of these kind of apps.
