Stockpile lets you buy and sell stocks like most other stock trading apps, but it also allows you to gift single shares of stock or buy fractional shares with a very low cent trade fee. Then the company builds portfolios, or motifs, based off related stocks. Luckily, there are apps designed specifically for novice investors — the technology is simple to understand, yet the features are comprehensive. The core features of the app are focused on tracking stocks you own and on your watchlist. The app allows you to trade and track your accounts anywhere from a mobile device and recent new features include customizable home screens, additional money management tools, advanced charting, daily market videos and option trading. While the ability to make small-dollar investments is appealing, the nature of the fee structure means your investing should be frequent.
