Is it really possible to pick the top dozen apps from more than 700,000 candidates? Let's just say it's a challenge, particularly when you're not focusing on a particular genre -- like, say, 3-D holographic coupon apps. Then again, there's nothing like a "best of" list to spur a spirited debate, complete with name calling, wild accusations and possibly even a virtual fistfight.

To choose this year's best iOS apps, we focused mostly business/enterprise tools, particularly those with relatively widespread appeal. Most of the apps we chose are work-oriented, but they're also useful when you're off-duty as well -- good news for the consumerization of IT beneficiaries who bring their iPhones and iPads to work. Another key criterion: The winning chosen apps didn't necessarily need to debut in 2012; rather, they had to fulfill a need common to a sizable percentage of the mobile computing crowd.

For example, one of the Top 12 apps provides a compelling alternative for motorists who've bailed on Apple's iOS 6 Maps app, which was a tad buggy when it debuted in September. Another winner provides a solid cloud storage solution for small and large businesses. And a third member of the Top 12 is particularly handy when you're traveling in a foreign country but can't speak the local language.

Our picks include a mix of free and paid apps. Users, of course, prefer free apps by a wide margin. A recent Gartner study shows that free apps will account for nearly 90% of total mobile app store downloads in 2012. Interestingly, user preference for free apps is expected to grow in the coming years. In fact, Gartner predicts that 93% of mobile app downloads will be free by 2016.

Now that Android has more or less caught up with iOS in the app numbers race -- each platform has more than 700,000 apps and counting -- the marketing emphasis will no doubt refocus on app quality rather than quantity. Apple arguably still has the edge in this area, particularly when it comes to tablet-specific apps and aesthetic appeal. For an iPad user, one of the joys of browsing the App Store is the ability to find a tablet-optimized version of the app you want. That's not always the case, of course, but it's far more common than on the Android side of things.
