My Favorite non gaming mobile app is Paypal! I love the paypal app!
this app has so many features, one of my favorites is the split bill button! It helps when you are dining with a friend or a group of people and you want to of course "split the bill" then it calculates how many people with the total cost and distributes it! Also i love how my balance is right at the top left hand corner, so that i know how much i have in my account! This app is great for showing purchase history and sending money! I love it, this is definitely in my mobile phone at all times!
