Document and publishing service Issuu has abandoned plans to launch an iOS app, following a third rejection by Apple, according to founder Martin Ferro-Thomsen. "Based on the latest rejection we donít think itís realistic that we can get it approved," he says. "We would have to make some changes weíre not comfortable with. We would have to restrict the community more than weíd like to. Itís really a sad day for us because we love Apple but itís their platform and App Store and we just live in it."
