Are task management apps helpful, or do they just add one more thing to your to-do list? We spent a week testing apps for a variety of smartphones to find out.
Remember the Milk
Our top pick, this app lets you sort tasks by urgency, due date, or tag. You can send reminders to yourself via text or e-mail. Unlike the other programs we tested, the app also lets you send tasks and reminders from Twitter. The app also syncs with Google Calendar and Gmail.
COST: There is a free basic version for iPhones; the professional version for Android phones and iPhones is $25 a year.
This nuanced iPhone app lets you determine how often you want to receive reminders about tasks related to individual projects. You can also create subsets of tasks -- say, those related to designing a marketing brochure. The app syncs with iPads, iPhones, and Mac computers.
The interface on this BlackBerry app looks a bit dated, but the program is easy to use. You can drag-and-drop tasks among neatly organized cascading folders. You can also create and delegate tasks using your BlackBerry e-mail account.
COST: $4.99 a month or a one-time fee of $60
