Cant Sync between iOs and OSX

I love this app on iOS, unfortunately I have not been able to get the mac client and the app to play nice. I have tried reinstalling the mac client, and both checking and unchecking icloud sync. Nothing seems to work. Looking at the developers website, the last entry to their blog was January, 2011, which sort of makes me wonder if this app is being actively maintained or not.
