YourCall ($9.95), which pops up only when you need it, works with whatever contact manager is installed; especially with the company's popular personal information manager Agendus, of course, for setting up meetings, tasks, follow-up calls, etc. If not Agendus, then YourCall will seek out the native application (usually Palm OS built-in contact manager) and bring up the corresponding dialog box.

You can set up preferences for the application to engages for certain contacts/phone numbers, or set which hours of the day for YourCall to be "on-call." It is available directly from the iambic Web site or as a an Over-the-Air download from here.

"YourCall is a fun little utility that helps close the loop when it comes to managing calls on your Palm OS-based Treo," said Adriano Chiaretta, chief operating officer at iambic, Inc. "It is especially useful when you are on the go, or have a million things going at once, because it gently steps you through the next steps so nothing falls through the cracks."
