I wasn't aware of StackMob. They seem to be a bit like Parse but with no API limits on the free tier (Parse's are pretty high) and better Core Data integration but a less rich API for doing things like saveEventually (which I find useful for logging as it should write eventually when network connectivity is restored even if it is the next run of the app).<p>I'm going to be implementing my own synchronisation code to allow multiple users/devices to edit a document at the same time and I'm not sure either of these platforms (Parse/Stackmob) are really suitable for that and I've read bad things about UIManagedDocument (iCloud with Core Data) and I want to be able to share between users too.<p>Does anyone know any good tutorials for handling these things well on any of these services or rolling my own server?
