It was last October when I had my Android phone. At first, I’m asking this: “Android phone for what?” I’m into calling and sending SMS only, I don’t need these apps!

But not anymore after I explored the Android Market! I realized that these applications will be useful in managing and organizing my daily routine. Here are the useful apps for me.
