@tzhongg As someone who trades casually, I thought it was super hard to just see how my holdings were doing at a glance with existing apps like E-Trade or Yahoo Finance. When I took a look around at apps in the App Store for finance, there was really no one who had nailed a real-time Portfolio app. Lots of people were just using spreadsheets to do this.
We started down this road and realized there are some really obvious features that just never got built (earnings push notifications, end of day summary notifications, etc). It seems weird that this stuff just didn't really exist before in app form. We've got a lot more good ideas coming as well =)
