Concerning the sync I think they're waiting to see if Apple plans to fix iCloud (with CoreData) in iOS 7 or if they must look for another way to do the sync. At least this is what I would do, we're very near WWDC I think it was wise to wait to see how it goes. Although I think what's more debatable was the decision to release the app now and not to wait few weeks or even september. Personally I would have tried (if as I think it's for them a side project) to wait the release of iOS 7 (and maybe require iOS 7) and add the sync functionality in version 1.0.
