A Siri for Your Finances? Digit Says Trust Me

Late last year, just in time for Christmas shopping, Rachel Rhoads got a nice surprise. One of her secret savings accounts had grown to $900 behind her back. Rhoads, a 37-year-old Los Angeles-based sales director for a jewelry line, has an account with Digit, a financial technology company with an algorithm that tracks users' income and spending patterns. It painlessly spirits small amounts of money out of checking and into a savings account every two or three days. "I just thought it was such a good idea, to set it and forget it," said Rhoads, who says she is "like a squirrel" in her approach to saving.
