Growing up, I loved the Swiss Army knife I got from my dad. They came in what seemed like a million variations. Mine had several knives, including the one that looked like a saw, as well as a corkscrew (not sure why Dad thought I needed that one), combination bottle opener/flathead screwdriver, a toothpick (ew!) and a pair of tweezers. It was incredible.
Today, the Swiss Army knife is still damn handy, but few one-size-fits-all tools can match the smartphone. We all know it can be used as a phone and to connect us to the Internet. It also has tons of apps that let us do everything from banking to putting pictures of cats on top of pictures of people. It's versatile.
But the truth is, even without the connectivity to the outside world, the smartphone has quite a number of really helpful apps -- some that are native to the iPhone and others -- that make it the modern-day technological version of the good old Swiss Army knife.
