I have exactly the same problem. I use OmniFocus on my Mac and iPhone. I have several repeating tasks such a watering plants etc. I check off tasks in desktop app or iPhone app. It's not always the same device. I've been using the OmniFocus server for syncing, but the repeating tasts starts duplicating. So now I'm trying sync by Bonjour, but I think this won't solve the problem! I started this sync method yesterday (I still check off some task on desktop app and some in iPhone app) and I already have duplicated task. It starts being very annoying. I hope the OmniFocus will take care of this, because the apps are not cheap. I don't want to be forced to change OmniFocus for Things.
