Android 4.0 "Ice Cream Sandwich" features the Roboto font
Roboto is a sans-serif typeface family introduced with Android Ice Cream Sandwich operating system. Google describes the font as "modern, yet approachable" and "emotional". The font is licensed under the Apache license. The entire font family was officially made available for free download on January 12, 2012 on the newly launched Android Design website. The family includes regular and oblique styles of Thin, Light, Regular, Medium, Bold, Black, and Condensed widths.
The font was designed entirely in-house at Google by Christian Robertson, an interface designer for Google, who previously had released an expanded Ubuntu-Title font through his personal type foundry Betatype.
Typography commentator Stephen Coles of typographica.org called Roboto “a Four-headed Frankenfont”, describing it as a “hodgepodge” of different typographic styles which end up not working well together. Other type design professionals called out obvious errors in accented glyphs, while John Gruber called the font a “Helvetica ripoff”.Joshua Topolsky, Editor-In-Chief of technology news and media network The Verge, describes the font as "clean and modern, but not overly futuristic – not a science fiction font".
