Updated
Simple, minimal and easy to use. Clear is one of the number one to-do apps available for iOS. There are no buttons or menus, you control the whole app just by fingertips, swipes and similar gestures. All to-dos are organized in lists. The iOS client can be synced with the OSX client via iCloud.
Specs
Pros
Pro Awesome interaction with gestures
Interaction design is the best feature of Clear, you can navigate the entire app via intuitive gestures. Clear takes advantage of touch screen features, using only finger gestures such as swiping, pulling or tapping to create a new task, remove one or editing one.
Pro iPad support
Clear now supports the iPad, and the app really shines when it comes to using this new expanse. Instead of showing you only a single list of lists or tasks, as the older iPhone-only version did, on an iPad the new Clear splits the main view into two columns: On the left is your master list of lists (containing, for example, lists for personal, work, and home); on the right is the list of tasks for whichever list you select.
Cons
Con Very restrictive
Clear is not as functional due to restrictions. For example, the 28 character task name limit does not allow all tasks to be named and described. Clear also does not feature reminders, calenders or app integration. Clears main function is being a to-do list without any extra functions. If its all you need, Clear may work for you. But, for those needing more features and organization, Clear is a bit lacking.
