If you’re looking for a great way to keep up with your investment portfolio, look no further. QFolio takes your real-time portfolio and watch lists wherever you go. It is free, and displays unlimited real-time quotes, pre-market and after-hours activity, charting and an exclusive, custom heat map.

This has got to be one of the best free apps available for the PlayBook. That is, if you have a portfolio to keep up-to-date on. Even if you don’t, it is still a great way to get real-time results on the performance of RIMM and other companies.
