<p>Many people have criticized Apple's first-party iOS apps and rightfully so but even if you find a suitable replacement, there isn't a way to change the default apps in iOS 6 for email, browsing and calendar, so most people stick with the Apple offerings.</p><p>Apple's calendar app is fine as a basic calendar and if you don't create many events in-app. But for business users it's barely acceptable and can be overly cumbersome to use.
