Rudder is a new personal finance service that differs from the dozens of other ones now available in two key ways: it presents a simplified overview of your available funds, which it calls “What’s Left,” and it delivers it (along with bill reminders and balance notifications) to your email inbox instead of requiring you to visit a website. Think of it as a highly customized “Very Short List” or “Daily Candy,” only the topic is always your current financial health.
