Mint's secure website downloads balances from your bank accounts, credit cards, and investments and lets you manually add any cash spending, then tracks monthly cash flow and outlines how your spending stacks up to your budget.
WIRED View cash flow by merchant or category, like Bills & Utilities and Shopping.
TIRED Can't set up a budget in-app, only on the website. Sneaks ads into the "advice" section.
