Nothing says mission accomplished like a big fancy "done" stamp.

Todo trumps the built-in iPhone task-management. It's a powerful, to-do checklist with multiple ways of tracking your objectives.

When you create a task in Todo, you pick which type of task it is: Normal, Call a Contact, Email a Contact, Visit a Location, or Visit a Website. All of the types except Normal will assist you when you're ready to complete the task, like dialing a contact for you or pre-addressing an email. You don't have to do any of the tasks within the program, but it's nice to have such a helping hand ready to go.

Task options make Todo versitaile. It handles due dates and times, repeating tasks, scaling priority, grouping in lists, tags, and more. You can customize the tags and terms to suit your specific needs. Once complete, you can strike through tasks in a few ways or just make them disappear. Best of all, the app syncs with online task management sites Toodledo and Remember the Milk, although there's no iCal connection. (Appigo promises that in January.)

Todo just works. It's simple to use and adeptly manages lots of tasks. We only wanted a harsher alarm process; Todo shows overdue tasks but doesn't warn us as we miss them.
