Sometimes we use apps and don't even pay attention to their capability of storing to iCloud. In fact, we don't really care. But, every now and then, and app pops up that provides some practical function using the iCloud. Piggy-Back.Me is one of those apps. I'm guilty of almost always running all of the battery out of my iPhone. On top of that, I never remember anyone's phone number anymore. It's all stored on my phone. Unfortunately, there have been times where I needed to call someone but had a near dead battery. This app allows me to easily store and access my contacts via the cloud on my iPad so I can call or text someone during those times where I run the battery out on my phone.
