Investing lets your money make more money for you no matter where you are or what you're doing. However, you do need to keep tabs on it, especially if you are an active trader.

Apps for tablets and smartphones have grown increasingly sophisticated and popular, enabling you to do market analysis, get tips and even make trades right from your mobile device. Many online stock trading platforms offer a mobile version. Here are 10 of the best stock apps that aren't dependent on an online trading service:

Best Apps for Trading

Robinhood: Whether you're a casual or serious trader, you know that fees can get expensive. Robinhood allows you to make trades for free for U.S.-listed securities. The app lets you place market, limit, stop-loss, stop limit and good-till-canceled orders. The transactions are SIPC protected up to $500,000.

Betterment: Betterment is a robo advisor that does the investing for you. You begin with a simple questionnaire, and the Betterment app selects a portfolio for you. It charges a management fee that is significantly smaller than those of a traditionally managed account. The program offers automated deposits, tax-efficient rebalancing of investments and automatic dividend reinvesting. Your account is SIPC protected up to $500,000, and you can withdraw funds at any time.

Wealthfront: Answer a few questions, and Wealthfront, an SEC-registered investment advisor, selects one of 20 portfolios that suits your investment goals. You need $500 to open the account, and you can link your bank account to your Wealthfront one for automatic investing. It also includes a portfolio review service to evaluate your other investments and make recommendations. This service is free for accounts up to $10,000; after that, it charges 0.25 percent a year.

Acorn: Acorn takes your spare change and invests it in a diversified portfolio of over 7,000 stocks and bonds. For example, if you spend $3.79 on coffee, it takes 21 cents from your account. Once you have amassed five dollars, it invests that for you. You can add recurring deposits or one-time deposits. The account is SIPC protected up to $500,000. You can track your account and withdraw money at any time.

Best Apps for Tracking & Analysis

Bloomberg: This app from one of the top financial news companies offers you news and market data on your smartphone or tablet. In addition to news articles and watchlists, you can watch Bloomberg Television Live or listen to audio interviews and analysis from around the world. It offers performance charts to track your holdings and the ability to identify leaders and laggers. You can customize the app and set alerts on stock positions.

Jstock: One of the most popular financial analysis apps, Jstock provides portfolio and dividend-management tools, information on 36 world stock markets, performance charts going back 10 years, world indexes and stock alerts.

MyStocks Portfolio and Widget: This handy app provides news, streams real-time quotes and provides charts. However, it can handle multiple portfolios, convert portfolios into a different currency, and lets you import and export data in CSV from Google Finance portfolios.
