Extreme Calendar has been released and is now on sale for over 66% off for this weekend only(May 21-22). Extreme Calendar has almost all of the main features of the Extreme Agenda calendar at a lower price. It then allows you to InApp purchase an upgrade to Extreme Agenda's full organizer features when you want to.
So give it a try! It is a great deal at its regular price and has more features than the other calendar apps out there, so yeah it can 'beat up' Calvetica and WeekCal, despite claims otherwise
And its a Universal App, so you will only ever buy it once.
And its an absolute steal at 99 cents this weekend...
(and Extreme Agenda is on Sale Too)
