Introduction

As college students who always live on a tight budget, we are thinking about how to optimize every penny we spend. Of course, google spread sheet is a nice tool to write down all our expenses and calculate the balance. However, with a handy useful app on your smartphone which is always around you, it will be easier and way more convenient to record and track your expenses.
