In case you've been living under a rock for the past two years, apps for iPads, iPhones and other smartphones can be extremely useful for almost any task and are often free. That said, sorting through the dross to find the best ones is not something most people have time for. Instead, check out meetingapps.com, which lists planner-approved apps for meetings. Thanks to James Spellos, founder and president of Meeting U. (meeting-u.com), for the suggestion.
