Font styles

[swharshbar]

I kinda revamped my phone using nova launcher prime and customized it to my taste. I was really bored with the stock launcher as well as now that my phone has some age, I wanted to give it a different feel. One thing I was really hoping for was a new font style for the phone. But I don't really see that option in nova launcher. I tried downloading several font app's from the app store, but none seem to work.

Is there a way to change the font style on our phones without rooting?
