Some notes on Input
Name: Refers to the name of something you're buying (e.g. coffee)
Price: Exactly what it sounds like. Make sure to format this as a number (e.g. 2.11)
Date: This is probably what you're here about. Many forms of input are acceptable. The one given in the defaults (e.g. July 23 2013) is the least ambiguous, and therefore probably the best idea. That said, the following would be equivalent (assuming it's the 25th of the same month and year):
July 23
jul 23
Tuesday
tue
Category: This is other thing you're likely here about. This is mainly for analysis purposes. I wanted to include some notion of a 'breakdown' functionality so that you can get some idea of where your monthly expenses are going, but it really doesn't make sense to do this on an item-by- item basis. So, when you add 'lunch' to the record, put it in the category 'food,' or 'eating out'. It's all a matter of how much information you want to record.
