Rarely an app comes along that warrants raving about, but I've found it. Agenda, a 99-cent impulse buy on the app store, is a replacement application for the Calendar app.
I'm definitely tired of the skeumorphic design of some of the stock iPad applications; so to see a modern, minimalist look on a fully-featured replacement is a good thing.
It's simple to use: swipe right-to-left to drill down to day view from week view, then appointment; right to left to back all the way out to hear view. The user can select what default view to see when they launch the app (I like the month view).
The app also features an innovative feature called Goals, which gives you the option to show very important milestones over the year ahead.
You can add events, confirm appointments (with customizable responses) and get the same alert notifications one expects with the calendar apps.
It also includes custom themes that allow a degree of personalization; thankfully, Savvy Apps has left out a skeumorph theme.
This app is also another example of Apple seriously relaxing its restrictions on apps that offer duplicate functionality. This is obviously a great thing for developers, as the shackles appear to be coming off.
Agenda is well worth the 99 cents for people engrossed in calendar management, but want a different option than the sometimes ugly look of iOS Calendar.
