Does anyone else use this app? I'm setting mine up today. It links with your checking account with your bank. So far, I'm content with their security and do not feel like my information is at risk. What it does is every time you use your debit card, it rounds up to the nearest dollar and uses the change for microinvestments. After a while, it adds up. If you get up to $500 you can make $1 million after 20 years.
