Mint.com is one of my most used websites. Mint's primary service allows users to track bank, credit card, investment, and loan balances and transactions through a single user interface, as well as create budgets and set financial goals.
It is a free budgeting and financial tracking app. Mint aggregates all of your different bank account information to one place.
The goal is to organize all of your finances in one place. Link all of your accounts with Mint to simplify. Set savings goals to improve your wealth. Set budgets to limit your spending. Review all transactions across all* of your accounts.
I recommend anyone with a bank account use Mint.com and the Mint mobile app.
