Sentigo’s Wall St Scanner app has garnered over 50,000 downloads in four weeks, and now ranks as the App Store’s No.1 investment app, the developers confirmed today.

“In a classic case of David vs. Goliath, the new stock market forecasting app has already overtaken financial app giants Yahoo Finance, CNBC and Bloomberg to secure pole position in the market,” Sentigo officials said.

Wall Street Scanner allows investors to track their stocks and market momentum from their iPhone, or iPad.

It aggregates stock market data, news and social media from over seven million websites and 15,000 sources, and uses intelligent algorithms to forecast tomorrow’s stock prices.

The app analyzes historical, financial and crowd sourced information and can potentially uncover new investment opportunities, the developers said.

Wall St. Scanner ultimately helps investors make smarter and more accurate trades by combining structured financial market data with unstructured market conversation parsing.

Updated to version 3.0 last week, Wall Street Scanner now sports live Twitter feeds for all the stocks in your portfolio, an improved news feed with higher resolution and visibility, and the ability to request to add stocks that aren’t currently featured.

Unlike other financial apps, Wall Street Scanner provides users with the bottom line on the top 2000 listed US stocks, as it is optimized solely for trading stocks.

Other key features include push notifications when there is a significant change to your favourite stocks’ indicators; trending news, mood analysis, buzz magnitude and analysts’ opinions; the ability to scan any specific stock out of the 2000+ traded stocks; detailed graphs of key indicators like standard ratios (such as put/call ratio and short ratio) and stock price over time.

Available as a free download for a limited time, the Wall Street Scanner app is compatible with iPhone, iPod touch, and iPad and requires iOS 4.0 or later.
