Not worth the $$$
I purchased this so I could seamlessly have a to do list on my Macbook Air, iPhone, and iPad. It is not set up to work that way - does not sync through iCloud - you are guided to use dropbox as a way to sync and after several attempts and having my partner try as well it would not sync. Waste of money. While watching a tutorial on the help site a tutorial for Wunderlist ran - a FREE app that actually WORKS!!!
