Roboto is a sans-serif typeface family developed by Google as the system font for its mobile operating system Android, and released in 2011 for Android 4.0 "Ice Cream Sandwich".
Roboto has a dual nature. It has a mechanical skeleton and the forms are largely geometric. At the same time, the font features friendly and open curves. While some grotesks distort their letterforms to force a rigid rhythm, Roboto doesn’t compromise, allowing letters to be settled into their natural width. This makes for a more natural reading rhythm more commonly found in humanist and serif types.
