I am amazed this only has 5 reviews right now. Perhaps its because the app doesnt demand you rate it every 5 seconds. Perhaps because its actually usable for those of us seeking calendar integration, repeating tasks, and nesting that were too busy to rate it.
Do yourself a favor and try it. It syncs to multiple apple devices too! Way better than ToDo, Evernote, and most of the other apps I have used.
