TMP (Time Manager Pad) is a one-of-a-kind organizer application for the Palm OS. It integrates calendar, appointments, and tasks in one screen. It loads blazingly fast. The latest version (v1.2) doesn’t exceed 300Kb in size. It supports icons, and thus has unofficially declared war on Agendus and DateBk. You should give it a try if you use either of the previous two.
