Five years ago, we (Charlie and Sarah) created PearBudget as a spreadsheet to help us track our spending. On a whim, we posted it online, in case other people might find it helpful. It was downloaded over 100,000 times, and was even written up in the Wall Street Journal, Popular Science, and dozens of popular websites and blogs. We decided to make a good thing better, so we turned PearBudget into a web-based application. Its now even friendlier and easier than it had been before.
