New York City start-up LearnVest is a personal-finance site for women — a fact you can figure out, as all the happy, prosperous people shown in the photos happen to be ladies. Mostly, though, it's full of tools and advice whose usefulness knows no gender. As with longtime personal-finance favorite Mint, you can link up your banking and credit-card accounts to monitor your income and spending, subscribe to e-mail "boot camps" on subjects like how to get out of debt and receive tips on insurance, real estate, retirement and more. There's even a section called Living Frugally, a title that resonates in an era when living within our means is the key to living well.
