Acorns

Acorns is a robo-advisor that makes it simple and easy to invest small amounts of money. Customers will pay $1 to invest in stocks and exchange-traded funds (ETFs) and up to $5 per month for add-on savings and spending accounts. Acorns key-feature is the ability to link debit card accounts and round-up purchases to incremental dollar amounts that are automatically invested into your Acorns portfolio.
