we're under. simple on the surface, complex underneath. so we made a font that works the same way. one font. does all the work. adapts to tiny screens, figma files, pdf forms, whatever you throw at it. auto line height. auto spacing. auto kerning. variable. open source. you know inter? helvetica? they're fine. but we wanted something that actually works as hard as we do. under is that font.
