We regularly highlight the free app giveaways on various stores, but this is perhaps the first time we can say that an app is free to download on all the major app stores - including Windows Phone, Windows PC's, and Mac OS X. The game in question is Stand O'Food, where players are tasked with building up a fast food empire. The game itself is actually 7 years old and spawned 2 sequels, but it contains over 100 levels to get through, and it's free. We've got links to all of the major app stores for you to grab a copy below. Thanks to Si__ @ HUKD!
