Agendus scans your contacts and populates them into its own contacts list, letting you easily add contacts to tasks and calendar events within the app. Agendus’s calendar improves upon the iPad’s standard calendar app by letting you easily view and add contacts, tasks, events, and birthdays without needing to switch to another app. It supports over-the-air syncing with Google Calendar, as well.

Agendus also includes a task management tool that works in conjunction with your calendar and contacts list, helping you keep track of your tasks when on the go with your iPad. Other features include the ability to set calendar icons for certain tasks and events, view a list of upcoming birthdays, and get weather forecasts."
