4. Barefoot World Atlas – Supposedly with better graphics than Google Earth and more geographic facts than your grandpa can recite, this is just another great way for kids to get excited about geography, and perhaps adults too. This $4.99 application is now free as well.
5. How To Cook Everything – My ability to cook Minute Rice in just 57 seconds is probably undermined with Mark Bittman’s accessible encyclopedia of every culture, dish and ingredient from around the world. Straightforward instructions, shopping list support and compatible with iPhone and iPad. Know it all, and more importantly, cook it all with this $9.99 application.
