AuqaCalendar is a replacement for the built in Series 60 Calendar application, and more like the Agenda from the Psion days than the lightweight Nokia replacement. Calendar, Tasks, Messages and Birthdays all feature in this powerful replacement, Check out the 1 Week Demo in the AAS Store.
Updated: AquaCalendar for Series 60
I have tried this, and though I like the idea of an agenda application like my psion does, I found this one just too cluttered. Havingn every single way of displaying a calendar in tabs that you just flick through by moving left and right I found just too much information, I like to choose one display format and stick to it, maybe using the others if and when needed. The left and right could have been used for navigation within the page displayed. The extra entry types are welcome, but I couldn't overlook the interface I am afraid :frown:
