The Best Stock Market Apps for Android

JStock's free version supports 27 world markets with individual stock history charts that go back 10 years with news for the stock. A chart of your stocks shows gains or losses and current bid prices, and there's a home widget to help you stay on top of your stocks. You can also set stock price alerts.

JStock's description in the Google Play app store says that the free version offers two technical analysis tools that show EMA and SMA, but I couldn't find them in the app. You will see some ads in the news feed in the free version. 

If you want to see a great looking summary chart, you'll have to either upgrade for $2.99 to get the chart only, or pay $7.99 to get these premium features:

• Ads removed.
• Cloud storage integration with JStock desktop software for Windows, Mac and Linux.
• Dividend chart, portfolio summary chart and zoomable history chart.
• Unlimited watchlists, portfolios and stocks news.
• Background stock alerts.
• Display foreign stock portfolio value in local currency based on exchange rate.

There is a seven-day free trial for the premium version.
