Of the many to-do apps available in the App Stores, one of the perennial favorites is Things from Cultured Code (US$9.99 for iPhone/iPod touch, $19.99 for iPad, $49.99 for Mac). While the cross-platform app has been lauded for its beautiful user interface and ease of use, there have been continuing complaints from users who want to be able to sync their To-Do tasks between devices. Other apps like Wunderlist (free) and OmniFocus have had cloud syncing for a while, and today Cultured Code has finally taken the wraps off of an implementation of cloud sync.
