Oliver from Information Architects has been teasing his company’s writing app for iPad for a while now, but the wait is over, and you can head straight to the iTunes App Store now and download it. It’s called Writer, and I had the great pleasure of pitching in on the beta testing phase, and can assure you that it’s a terrific writing app. Those of you who already follow Oliver’s writings about typography on the iPad (on the iA blog and on Twitter) know that he’s quite passionate on the subject, and that concern is in full evidence in Writer. And if you’re still not convinced, then Oliver lays it all out on the table for you.
