Schwab Mobile

Charles Schwab’s iPhone app hits a sweet spot between ease of use and power-user functionality. It’s ideal for both casual traders and serious investors, providing access to a wide range of investments, including stocks, ETFs, mutual funds, and more.

Not only that, but it’s also a great app if you’re starting with a smaller amount of cash. Schwab Mobile offers “stock slices,” which allow you to buy fractional shares of S&P 500 companies, which is ideal for those trying to build a diversified portfolio on a budget.

Additionally, if you’re someone who likes to set it and forget it, Schwab also offers an Intelligent Portfolios feature, an automated portfolio advisor that helps you build and adjust your portfolio as needed.
