You don't have to check off many boxes to buy and sell stocks. It's now as simple as downloading an app, answering a few questions, and making your first deposit to fund a trade. When choosing an app for investing, it's essential to look past the fundamentals since stock trading is primarily the same across different companies. Instead, look at what each service provides beyond the basics when choosing the one that's right for you.

In selecting the best stock trading apps for iOS 15 and iPadOS 15 for iPhone and iPad, respectively, we narrowed our choices by looking at:

  • The cost to invest
  • Whether fractional shares are supported
  • Account minimums
  • Range of available investments options
  • Account types offered
  • Access to research content
