Sometimes a glowing product write-up and a pile of random reviews just isn't enough when it comes to considering which apps are deserving of your cash. You want to get hands on. So Apple has introduced a Try Before You Buy in its App Store to do just that.Sadly, it doesn't allow you to have a go at just about any premium app on offer, there's a limited number of options out there. Specifically, according to Mashable, the section only contains 'lite' or ad-supported versions of apps whose full versions are in the pay section of the store. So iff the app doesn’t have a free version already in the App Store, you can't try it.Whicb means if (for example) you want to test out one of the premium football manager games...well, tough. You'll have to buy it and hope it's a good one you've picked. The lite versions, as the name suggests, also don't have the full range of features either. So you're not getting a full idea of how it works anyway. Maybe Apple wants to check out Android's 24-hour returns policy for how a try out system should work.Still, it's better than nothing and possibly a tentative first step rather than the finished product. You can find it under the 'Free on the App Store' heading, with around 98 apps currently housed within it, including Grand Theft Auto: Chinatown, Metal Gear Solid Touch and Labyrinth 2 plus free adaptations of apps such as Moodagent and AccuTerra.
