About iA Writer Quattro.
iA Writer Quattro is the four-width member of the iA Writer type family, built on IBM Plex and bundled with the iA Writer apps. Its four character widths bring it closer to proportional type while retaining wider word spaces and monospaced punctuation.
Compared with Mono and Duo, Quattro uses less space on small screens and produces a cleaner, more regular text image.
