Any feedback on my new stock app.

Hey Indie Hackers,

Would be super grateful to anyone who is willing to give me feedback on my recently released stock app Spulse. The purpose of the app is to give users a birds-eye realtime view of the market by using heat maps of each of the major sectors. I've gotten a fair amount of solid feedback from friends but would love to hear from anyone else interested in the market. So far I've gotten a few hundred downloads with solid ratings but not too much direct feedback.
