Checkbook (Android) app for $0.99

It's time to stop giving your bank free money from overdraft fees and nonsensical charges because of poor money management. It's easier than you think to handle your finances. Checkbook takes the place of a paper checkbook. Simply add an account with its name and starting balance. You can add as many accounts as you like. Choose from seven currencies, and put password protection on the app. You can also restore previous balances, and create a backup for your accounts.
