Acorns is a new investment app for iPhone that invests small amounts of money from your everyday transactions. Connecting to your credit or debit card, Acorns rounds up your transactions, taking the remaining "spare change" and investing it in a stock portfolio.

Acorns allows you to choose what type of portfolio you invest in. It can range from very conservative to very aggressive. You can also check the growth of your investments over time, and how they are predicted to grow. In addition to investing your spare change, you can deposite as much as you want at any given time. You can also set up recurring payments on a daily, weekly, or monthly basis. You can also withdraw money from your investment any time you want.

Acorn is free to download, with a $1 per month charge after you invest, in addition to any management fees that need to be charged. You can find Acorn on the App Store right now.
