Love it
I use this application a lot for work (reasearch analyst at a small investment management shop). It is a great go-to to keep track of key equities and run quick lookups for basic quant data, technical analysis, and fundamentals. Provides good links for deeper reasearch and has a crisp presentation. While I primarily use a PC at work, this is my go-to when I am working out of the office and using my Mac. Highly recommended app.
