The Business Insider recently posted an article that listed some of the best apps for wall streeters. I thought I would share a couple of them here:
S&P Capital IQ
This free iPad app allows users to track stocks on the S&P 500.

Instapaper
This app is available on most devices at a cost of $3.99. Save those financial articles to read while you are on the go. I love this app especially on the metro where I have no service at all.

Paper
This free iPad app is great if you need to teach somebody how to trade stocks or explain a new trading strategy.

Zite
This free iPad app allows you to curate a subscription of articles based on your settings and what you want to read.

Also check out the best trading apps for the iPad and the 10 stock trading apps for your iPhone.
