Cons
Con Extremely buggy
Around mid-2015 Downcast implemented some code that started to leave infinite loop processes that have the potential to cause the phone to heat up, lag, crash Downcast, or crash other apps. The bugs have only continued to get worse. Go with Overcast or Pocket Casts, or even Podcatcher for the Downcast feel.
Con Doesn't sync with iTunes
Con Needs root (by design)
Needs root to update the hosts file.
Con Won't block same domain ads
Because the host file can only redirect domains, if the ad and content are on the same domain the ad will be displayed.
